Abstract
BACKGROUND Basal cell hyperplasia is commonly observed in nasal polyp epithelium of eosinophilic chronic rhinosinusitis (eCRS). We examined the function and mechanisms of basal cell hyperplasia in the pathophysiology of eCRS. METHODS We found that normal human bronchial epithelial (NHBE) cells obtained basal cell characteristics when cultured with PneumaCult™-Ex Plus Medium. Most of the cells passaged three times expressed basal cell surface markers CD49f and CD271 by flow cytometry, and basal cell nuclear marker p63 by immunohistochemical staining. We named these NHBE cells with basal cell characteristics cultured Basal-like cells (cBC), and NHBE cells cultured with BEGM™ cultured Epithelial cells (cEC). The characteristics of cBC and cEC were examined and compared by RNA sequencing, RT-PCR, ELISA, and cell proliferation studies. RESULTS RNA sequencing revealed that cBC showed higher gene expression of thymic stromal lymphopoietin (TSLP), IL-8, TLR3, and TLR4, and lower expression of PAR-2 compared with cEC. The mRNA expression of TSLP, IL-8, TLR3, and TLR4 was significantly increased in cBC, and that of PAR-2 was significantly increased in cEC by RT-PCR. Poly(I:C)-induced TSLP production and LPS-induced IL-8 production were significantly increased in cBC. IL-4 and IL-13 stimulated the proliferation of cBC. Finally, the frequency of p63-positive basal cells was increased in nasal polyp epithelium of eCRS, and Ki67-positive proliferating cells were increased in p63-positive basal cells. CONCLUSIONS Type 2 cytokines IL-4 and IL-13 induce basal cell hyperplasia, and basal cells exacerbate type 2 inflammation by producing TSLP in nasal polyp of eCRS.

Abstract
While cardiovascular comorbidities can affect the outcomes of a variety of conditions, to our knowledge, few studies have evaluated their impact on non-melanoma skin cancers (NMSC). We studied the National Inpatient Sample to evaluate the impact of cardiovascular comorbidities on NMSC hospitalizations. Our findings displayed higher cost of care (Beta 5053; SE 1150; P < 0.001), length of stay (Beta 1.8; SE 0.394; P < 0.001), and mortality (aOR 2.51; CI 1.49-4.21; P < 0.001) in patients with NMSC who had an associated cardiovascular comorbidity. Specifically, patients with cerebrovascular disease (aOR 3.52; CI 1.18-10.5; P = 0.024), heart failure (aOR 4.02; CI 2.29-7.05; P < 0.001), complicated hypertension (OR 2.05; CI 1.16-3.61; P = 0.013), and pulmonary circulation disease (aOR 3.33; CI 1.13-9.78; P = 0.029) demonstrated greater odds of mortality.

Abstract
The immune system plays a key role in the suppression and progression of basal cell carcinoma (BCC). The primary aetiological factor for BCC development is exposure to ultraviolet radiation (UVR) which, particularly in lighter Fitzpatrick skin types, leads to the accumulation of DNA damage. UVR has roles in the generation of an immunosuppressive environment, facilitating cancer progression. Rates of BCC are elevated in immunosuppressed patients, and BCC may undergo spontaneous immune-mediated regression. Histologic and immunohistochemical profiling of BCCs consistently demonstrates the presence of an immune infiltrate and associated immune proteins. Early studies of immune checkpoint inhibitors reveal promising results in BCC. Therefore, the host immune system and tumor responses to it are important in BCC pathogenesis. Understanding these interactions will be beneficial for disease prognostication and therapeutic decisions.

Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a type 2 (T2) inflammatory disease associated with an increased number of airway basal cells (BCs). Recent studies have identified transcriptionally distinct BCs, but the molecular pathways that support or inhibit human BC proliferation and differentiation are largely unknown. OBJECTIVE We sought to determine the role of T2 cytokines in regulating airway BCs. METHODS Single-cell and bulk RNA sequencing of sinus and lung airway epithelial cells was analyzed. Human sinus BCs were stimulated with IL-4 and IL-13 in the presence and absence of inhibitors of IL-4R signaling. Confocal analysis of human sinus tissue and murine airway was performed. Murine BC subsets were sorted for RNA sequencing and functional assays. Fate labeling was performed in a murine model of tracheal injury and regeneration. RESULTS Two subsets of BCs were found in human and murine respiratory mucosa distinguished by the expression of basal cell adhesion molecule (BCAM). BCAM expression identifies airway stem cells among P63+KRT5+NGFR+ BCs. In the sinonasal mucosa, BCAMhi BCs expressing TSLP, IL33, CCL26, and the canonical BC transcription factor TP63 are increased in patients with CRSwNP. In cultured BCs, IL-4/IL-13 increases the expression of BCAM and TP63 through an insulin receptor substrate-dependent signaling pathway that is increased in CRSwNP. CONCLUSIONS These findings establish BCAM as a marker of airway stem cells among the BC pool and demonstrate that airway epithelial remodeling in T2 inflammation extends beyond goblet cell metaplasia to the support of a BC stem state poised to perpetuate inflammation.

Abstract
BACKGROUND Achieving adequate surgical margins and preventing recurrence are important in the treatment of basal cell carcinoma (BCC). OBJECTIVES The objectives of this study were to evaluate the adequacy of surgical margins and the re-excision rates in patients with primary BCC who underwent standard surgical treatment using our proposed algorithm and to define the risk factors in patients with recurrent BCC. METHODS The medical records of patients who were histopathologically diagnosed with BCC were reviewed. An algorithm created based on previous literature was used to determine the distribution of optimal surgical margins adequacy and re-excision rates. RESULTS Statistically significant differences were observed between the cases with and without recurrence in age at diagnosis (p=0.004), tumor size (p=0.023), tumor location in the H zone of the face (p=0.005), and aggressive histopathological subtype (p=0.000). When the tumors were evaluated for adequacy of deep and lateral surgical margins and re-excision rates, higher rates of adequate excision (457 cases, 68.0%) and re-excision (43 cases, 33.9%) were noted for tumors in the H or M zone. STUDY LIMITATIONS Inadequate follow-up of newly diagnosed patients in terms of recurrence and metastasis and the retrospective application of our proposed algorithm are the limitations of the present study. CONCLUSIONS Our results showed that if BCC was detected at an early age and at an early stage, recurrence was lower. The H and M zones were the regions with the highest rates of optimal surgical outcomes.

Abstract
Epithelial cells orchestrate a series of intercellular signaling events in response to tissue damage. While the epididymis is composed of a pseudostratified epithelium that controls the acquisition of male fertility, the maintenance of its integrity in the context of tissue damage or inflammation remains largely unknown. Basal cells of the epididymis contain a primary cilium, an organelle that controls cellular differentiation in response to Hedgehog signaling cues. Hypothesizing its contribution to epithelial homeostasis, we knocked out the ciliary component ARL13B in keratin 5-positive basal cells. In this model, the reduced size of basal cell primary cilia was associated with impaired Hedgehog signaling and the loss of KRT5, KRT14, and P63 basal cell markers. When subjected to tissue injury, the epididymal epithelium from knock-out mice displayed imbalanced rates of cell proliferation/apoptosis and failed to properly regenerate in vivo. This response was associated with changes in the transcriptomic landscape related to immune response, cell differentiation, cell adhesion, and triggered severe hypoplasia of the epithelium. Together our results indicate that the ciliary GTPase, ARL13B, participates in the transduction of the Hedgehog signaling pathway to maintain basal cell stemness needed for tissue regeneration. These findings provide new insights into the role of basal cell primary cilia as safeguards of pseudostratified epithelia.

Abstract
PURPOSE To date, there are no studies on healthcare resource utilization (HRU) and costs for treating periocular basal cell carcinoma (pBCC). We investigated real-world HRU and costs of patients with limited versus extensive pBCC. DESIGN This was a retrospective cost analysis. METHODS Administrative claims database was mined for basal cell carcinoma (BCC)-related claims from January 2011 to December 2018. Patients had ≥1 inpatient or ≥2 outpatient nondiagnostic claims for pBCC ≥30 days apart, ≥6 months of continuous enrollment in a health plan before the index date, and ≥18 months of continuous enrollment after the index date. Patients were categorized by disease severity (limited or extensive) using Current Procedural Terminology codes. A total of 1368 patients were propensity matched 1:1 for limited and extensive pBCC (n = 684 each). Outcomes were cost and HRU measures during the 18-month follow-up period. RESULTS Patients with extensive disease had a higher number of outpatient visits (32.47 vs 28.81; P < .0001), radiation therapies (0.53 vs 0.17; P = .001), surgeries (1.82 vs 1.24; P < .001), days between first and last surgery (40.82 vs 16.51 days; P < .001), outpatient pBCC claims (3.89 vs 3.38; P < .001), and days between pBCC claims (170.43 vs 144.01 days; P < .001). Patients with extensive disease incurred higher total all-cause costs ($36,986.10 vs $31,893.13; P = .02), outpatient costs ($20,450.26 vs $16,885.87; P = .005), radiation therapy costs ($314.28 vs $89.81; P = .01), and surgery costs ($3,697.08 vs $2,585.80; P < .001) than patients with limited disease. CONCLUSIONS Patients with extensive pBCC incurred higher costs, greater HRU, and longer time between first and last surgery versus patients with limited pBCC. Early diagnosis and early treatment of pBCC have economic benefits.

Abstract
Basal cell carcinomas have been reported to arise within several different tumors. Without careful attention to detail, basal cell carcinomas may go unnoticed when presenting within or directly adjacent to another distinct tumor. The increased use and accessibility of dermoscopy has allowed dermatologists to detect skin cancers that might otherwise be undetected by the naked eye. This case report details a collision, detected by dermoscopy, of a basal cell carcinoma developing within a long-standing hemangioma (cherry angioma) on the left lower eyelid of a 75-year-old man.

Abstract
Mammary gland is an outstanding system to study the regulatory mechanisms governing adult epithelial stem cell activity. Stem cells in the basal layer of the mammary gland fuel the morphogenesis and regeneration of a complex epithelial network during development and upon transplantation. The self-renewal of basal stem/progenitor cells is subjected to regulation by both cell-intrinsic and extrinsic mechanisms. Nfatc1 is a transcription factor that regulates breast tumorigenesis and metastasis, but its role in mammary epithelial development and stem cell function has not been investigated. Here we show that Nfatc1 is expressed in a small subset of mammary basal epithelial cells and its epithelial-specific deletion results in mild defects in side branching and basal-luminal cell balance. Moreover, Nfatc1-deficient basal cells exhibit reduced colony forming ability in vitro and somewhat compromised regenerative potential upon transplantation. Thus, our study provides evidence for a detectable yet non-essential role of Nfatc1 in mammary epithelial morphogenesis and basal stem/progenitor cell self-renewal.

Abstract
Stem-cell containing mammary basal epithelial cells exist in a quasi-mesenchymal transcriptional state characterized by simultaneous expression of typical epithelial genes and typical mesenchymal genes. Whether robust maintenance of such a transcriptional state is required for adult basal stem cells to fuel self-renewal and regeneration remains unclear. In this work, we utilized SMA-CreER to direct efficient basal cell-specific deletion of Ovol2, which encodes a transcription factor that inhibits epithelial-to-mesenchymal transition (EMT), in adult mammary gland. We identified a basal cell-intrinsic role of Ovol2 in promoting epithelial, and suppressing mesenchymal, molecular traits. Interestingly, Ovol2-deficient basal cells display minimal perturbations in their ability to support tissue homeostasis, colony formation, and transplant outgrowth. These findings underscore the ability of adult mammary basal cells to tolerate molecular perturbations associated with altered epithelia-mesenchymal plasticity without drastically compromising their self-renewal potential.

Abstract
Background Basal cell carcinoma (BCC) is a common skin cancer often curable by excision; however, for patients with BCC around the eye, excision places visual organs and function at risk. In this article, we test the hypothesis that use of the hedgehog inhibitor vismodegib will improve vision‐related outcomes in patients with orbital and extensive periocular BCC (opBCC). Materials and Methods In this open‐label, nonrandomized phase IV trial, we enrolled patients with globe‐ and lacrimal drainage system–threatening opBCC. To assess visual function in the context of invasive periorbital and lacrimal disease, we used a novel Visual Assessment Weighted Score (VAWS) in addition to standard ophthalmic exams. Primary endpoint was VAWS with a score of 21/50 (or greater) considered successful, signifying globe preservation. Tumor response was evaluated using RECIST v1.1. Surgical specimens were examined histologically by dermatopathologists. Results In 34 patients with opBCC, mean VAWS was 44/50 at baseline, 46/50 at 3 months, and 47/50 at 12 months or postsurgery. In total, 100% of patients maintained successful VAWS outcome at study endpoint. Compared with baseline, 3% (95% confidence interval [CI], 0.1–15.3) experienced major score decline (5+ points), 14.7% (95% CI, 5 to 31.1) experienced a minor decline (2–4 points), and 79.4% experienced a stable or improved score (95% CI, 62.1–91.3). A total of 56% (19) of patients demonstrated complete tumor regression by physical examination, and 47% (16) had complete regression by MRI/CT. A total of 79.4% (27) of patients underwent surgery, of which 67% (18) had no histologic evidence of disease, 22% (6) had residual disease with clear margins, and 11% (3) had residual disease extending to margins. Conclusion Vismodegib treatment, primary or neoadjuvant, preserves globe and visual function in patients with opBCC. Clinical trail identification number.NCT02436408. Implications for Practice Use of the antihedgehog inhibitor vismodegib resulted in preservation of end‐organ function, specifically with regard to preservation of the eye and lacrimal apparatus when treating extensive periocular basal cell carcinoma. Vismodegib as a neoadjuvant also maximized clinical benefit while minimizing toxic side effects. This is the first prospective clinical trial to demonstrate efficacy of neoadjuvant antihedgehog therapy for locally advanced periocular basal cell carcinoma, and the first such trial to demonstrate end‐organ preservation. This article reports the results of a prospective clinical trial of vismodegib for patients with basal cell carcinoma occurring in the orbital and periocular regions to assess whether such treatment helps to preserve visual organs and function.

Abstract
Communication among epididymal epithelial cells creates the best luminal
condition where spermatozoa mature, transport and are stored. Vacuolar ATPase
(V-ATPase) and cytokeratin 5 (KRT5) have been used as signal indicators for
clear and basal cells of the epididymal epithelium, respectively, in mice, rats,
bats, and pigs; however, these two markers have not yet been described in the
epididymis of bulls. Here, we examined the presence and distribution of the B1
subunit of V-ATPase (B1-VATPase) and KRT5 in the distinct regions of adult
bovine epididymides, specifically, the caput, corpus, and cauda.
Immunofluorescence staining and confocal microscopy showed that narrow
shaped-clear cells were placed in the caput and corpus regions of the bovine
epididymis; however, they were absent in the cauda epididymis. In addition,
B1-VATPase was highly expressed in the cauda spermatozoa; however, it was rarely
detected in the caput spermatozoa. On the other hand, KRT5-positive cells, basal
cells, were maintained beneath the basal lamina and they had the traditional
form with a dome-shaped morphology from the caput to cauda region of the bovine
epididymis. The co-expression of B1-VATPase and KRT5 was confined to basal cells
placed in the basal region of the epithelium. In summary, 1) clear cells were
present with region-specific localization, 2) B1-VATPase was present in the
corpus and cauda spermatozoa but absent in the caput, 3) co-expressed cells with
B1-VATPase and KRT5 were present in the adult bovine epididymis, and 4)
B1-VATPase was not a specific marker for clear cells in the bovine epididymis.
Therefore, the perfect epididymal luminal condition created by the specific
expression and localization patterns of B1-VATPase might be necessary to obtain
fertilizing capacity of spermatozoa in the bovine epididymis.

Abstract
BACKGROUND The conducting airway epithelium is repaired by tissue specific stem cells (TSC). In response to mild/moderate injury, each TSC repairs a discrete area of the epithelium. In contrast, severe epithelial injury stimulates TSC migration and expands the stem cell's reparative domain. Lung transplantation (LTx) can cause a moderate/severe airway injury and the remodeled airway contains a chimeric mixture of donor and recipient cells. These studies supported the hypothesis, LTx stimulates TSC migration resulting in epithelial chimerism. We tested this hypothesis in cystic fibrosis (CF) LTx patients. METHODS Airway mucosal injury was quantified using bronchoscopic imaging and a novel grading system. Bronchial brushing was used to recover TSC from 10 sites in the recipient and allograft airways. TSC chimerism was quantified by short tandem repeat analysis. TSC self-renewal and differentiation potential were assayed using the clone forming cell frequency and air-liquid-interface methods. Electrophysiology was used to determine if TSC chimerism altered epithelial ion channel activity. RESULTS LTx caused a mild to moderate airway mucosal injury. Donor and recipient TSC were identified in 91% of anastomotic sites and 93% of bronchial airways. TSC chimerism did not alter stem cell self-renewal or differentiation potential. The frequency of recipient TSC was proportional to CF Transmembrane Conductance Regulator (CFTR)-dependent ion channel activity and 33% of allograft regions were at risk for abnormal CFTR activity. CONCLUSIONS LTx in CF patients stimulates bidirectional TSC migration across the anastomoses. TSC chimerism may alter ion homeostasis and compromise the host defense capability of the allograft airway epithelium.

Abstract
Squamous cell carcinoma (SCC) is an aggressive malignancy that can originate from various organs. TP63 is a master regulator that plays an essential role in epidermal differentiation. It is also a lineage-dependent oncogene in SCC. ΔNp63α is the prominent isoform of TP63 expressed in epidermal cells and SCC, and overexpression promotes SCC development through a variety of mechanisms. Recently, ΔNp63α was highlighted to act as an epidermal-specific pioneer factor that binds closed chromatin and enhances chromatin accessibility at epidermal enhancers. ΔNp63α coordinates chromatin-remodeling enzymes to orchestrate the tissue-specific enhancer landscape and three-dimensional high-order architecture of chromatin. Moreover, ΔNp63α establishes squamous-like enhancer landscapes to drive oncogenic target expression during SCC development. Importantly, ΔNp63α acts as an upstream regulator of super enhancers to activate a number of oncogenic transcripts linked to poor prognosis in SCC. Mechanistically, ΔNp63α activates genes transcription through physically interacting with a number of epigenetic modulators to establish enhancers and enhance chromatin accessibility. In contrast, ΔNp63α also represses gene transcription via interacting with repressive epigenetic regulators. ΔNp63α expression is regulated at multiple levels, including transcriptional, post-transcriptional, and post-translational levels. In this review, we summarize recent advances of p63 in epigenomic and transcriptional control, as well as the mechanistic regulation of p63.

Abstract
Background We evaluated the clinical efficacy and prognosis of muscle-invasive bladder cancer according to the basal/squamous-like (BASQ) classification system based on immunohistochemical staining [CK5/6(+), CK14(+), GATA3(−), and FOXA1(−)]. Methods One hundred patients diagnosed with muscle-invasive bladder cancer (cT2-4 N0-3 M0) were included in the study. All patients underwent radical cystectomy after transurethral removal of bladder tumor. Immunostaining was performed for CK5/6, CK14, FOXA1, and GATA3 antibodies on tissue microarray slides, and expression patterns were quantitatively analyzed using a scanning program. Results The median follow-up time was 77.4 (interquartile range: 39–120.9) months. The mean age of the patients was 65.1 ± 11.2 years. FOXA1 or CK14 expression greater than 1% was respectively positively and negatively correlated with overall survival (OS; p = 0.011 and p = 0.042, respectively), cancer-specific survival (CSS; p = 0.050 for both), and recurrence-free survival (RFS; p = 0.018 and p = 0.040, respectively). For CK5/6+ and GATA3- or FOXA1- expression, 10% CK5/6+ cells were negatively correlated with OS (p = 0.032 and p = 0.039, respectively) and with RFS in combination with FOXA1- only (p = 0.050). Conclusions In this study, CK14 expression was associated with a poor prognosis. The new classification system of bladder cancer based on molecular characteristics is expected to helpful tool for the establishment of personalized treatment strategies and associated prediction of therapeutic responses.

Abstract
BACKGROUND KRAS is a GTPase that activates pathways involved in cell growth, differentiation and survival. In normal cells, KRAS-activity is tightly controlled, but with specific mutations, the KRAS protein is persistently activated, giving cells a growth advantage resulting in cancer. While a great deal of attention has been focused on the role of mutated KRAS as a common driver mutation for lung adenocarcinoma, little is known about the role of KRAS in regulating normal human airway differentiation. METHODS To assess the role of KRAS signaling in regulating differentiation of the human airway epithelium, primary human airway basal stem/progenitor cells (BC) from nonsmokers were cultured on air-liquid interface (ALI) cultures to mimic the airway epithelium in vitro. Modulation of KRAS signaling was achieved using siRNA-mediated knockdown of KRAS or lentivirus-mediated over-expression of wild-type KRAS or the constitutively active G12 V mutant. The impact on differentiation was quantified using TaqMan quantitative PCR, immunofluorescent and immunohistochemical staining analysis for cell type specific markers. Finally, the impact of cigarette smoke exposure on KRAS and RAS protein family activity in the airway epithelium was assessed in vitro and in vivo. RESULTS siRNA-mediated knockdown of KRAS decreased differentiation of BC into secretory and ciliated cells with a corresponding shift toward squamous cell differentiation. Conversely, activation of KRAS signaling via lentivirus mediated over-expression of the constitutively active G12 V KRAS mutant had the opposite effect, resulting in increased secretory and ciliated cell differentiation and decreased squamous cell differentiation. Exposure of BC to cigarette smoke extract increased KRAS and RAS protein family activation in vitro. Consistent with these observations, airway epithelium brushed from healthy smokers had elevated RAS activation compared to nonsmokers. CONCLUSIONS Together, these data suggest that KRAS-dependent signaling plays an important role in regulating the balance of secretory, ciliated and squamous cell differentiation of the human airway epithelium and that cigarette smoking-induced airway epithelial remodeling is mediated in part by abnormal activation of KRAS-dependent signaling mechanisms.

Abstract
This article reviews the most common nonmelanoma skin cancers affecting the head and neck region. Although the most common of these malignancies rarely result in mortality, local morbidity caused by the tumors and their extirpation cannot be underestimated. Complete tumor extirpation with pathologically confirmed negative margins is the gold standard. Regional and distant metastases are rare, but must be treated appropriately should they occur. Although reconstructive surgery can be life changing for the patients and rewarding for the clinicians, it behooves the treating surgeons to remain true to oncologic principles above all else.

Abstract
Plant zygotes usually undergo asymmetrical cell division, giving rise to the formation of two daughter cells with distinct developmental cell fate. The small apical cell will develop into the major part of embryo proper, whereas the larger basal cell will divide to form a transient suspensor. Thus, the apical and basal cell lineages are an excellent model to study cell fate determination in relation to zygote polarity. However, the molecular mechanism underlying the differentiation of two distinct cell lineages is not yet understood, possibly due to the technique limitations. Previously, we have established a protocol for isolating apical cell and basal cell for cDNA library construction in tobacco. However, the method for isolating tiny Arabidopsis embryos has long been considered much more difficult. Here, we present a detailed protocol for isolating early Arabidopsis proembryos and separating apical and basal cell lineages of proembryos, which allow us to establish cell lineage-specific transcriptomes of early proembryos.

Abstract
Background The alar and nasal tip are important subunits of the nose. Determining the optimal procedure for reconstructing a cutaneous defect in a nasal subunit depends on several factors including size, location, and involvement of deep underlying structures. We treated cutaneous defects after tumor ablation in the alar and nasal tip with a local flap, using an S-shaped design and a modified V-Y advancement flap with a croissant shape. Methods We analyzed 36 patients with skin tumors who underwent flap coverage after tumor ablation. Rotation flaps were used in 26 cases and croissant-shaped V-Y advancement flaps were used in 10 cases. The primary cause of the defects was skin cancer, except for one benign tumor. Results The mean patient age was 71 years. The size of the defects ranged from 0.49 cm2 to 3.5 cm2. No recurrence of skin cancer was noted and all flaps lasted until the end of follow-up. Partial desquamation of the epidermis was noted in one case. The postoperative appearance for most patients was excellent, objectively and subjectively. Conclusion For cutaneous defects of up to about 4.0 cm2 of the alar and nasal tip, local flaps using our methods offered a good cosmetic and therapeutic result. The main advantage of our flaps is the minimal dissection required compared to bilobed and other local flap methods. We believe our flaps are a suitable option for alar and nasal tip reconstruction.

Abstract
The human airway epithelium is regenerated by basal cells. Thus, basal cell therapy has the potential to cure cystic fibrosis (CF) lung disease. We previously reported that the human basal cells repopulated the mouse airway epithelium after transplantation, and we estimated that 60 million cells would be needed to treat a human patient. To further develop cell therapy, we compared the proliferation potential of non‐CF and CF tissue‐derived bronchial basal cells. Three methods were used: regenerative cell frequency, burst size, and cell division frequency. Second, we used a serial passage strategy to determine if CF basal cells could be amplified to the estimated therapeutic dose. These studies evaluated that tissue‐derived bronchial basal cells and the basal cells that were recovered by brushing bronchial airways or the nasal respiratory epithelium. Finally, we used the limiting dilution method to isolate non‐CF and CF basal cell clones. The proliferation assays and the air‐liquid‐interface differentiation method were used to determine if cell amplification altered the proliferation and/or differentiation potential of clonal isolates. We demonstrate that: (a) non‐CF and CF basal cell proliferation is similar, (b) CF basal cells can be amplified to a therapeutic cell dose, and (c) amplified non‐CF and CF basal cell clones differentiate normally. Despite these encouraging findings, we also find that the cell amplification process depletes the regenerative basal cell pool. Analysis of basal cell clones indicates that serial passage selects for long‐lived basal cells and raise the possibility that prospective isolation of these stem‐like cells will improve the efficacy of cell replacement therapy. stem cells translational medicine2019;8:225&235

Abstract
The incidence of basal cell carcinoma (BCC) is increasing as the population is aging and doubles every ten years. Surgery is the first-line treatment of BCC. Dermatological surgery is an oncological skin surgery whose first objective is to obtain a complete resection of the tumor. Its aim is also to reconstruct the defect using the optimal repair technique for the best cosmetic and scarring outcome and without functional impairment. The dermatological approach with the "oncological reading" of cutaneous tumors constitutes the essential preliminary time to the diagnosis of BCC and the identification of its limits. The perfect knowledge of the security margins in accordance with the guidelines allows a complete excision and a reconstruction in one stage under local anesthesia in the majority of cases. The surgical treatment must use 3D histology techniques or micrographic surgery to manage difficult cases of aggressive BCC in high risk zone or recurrence. Management of very aggressive BCC or locally advanced BCC is discussed in a multidisciplinary consultation by assessing the benefit/risk ratio of the surgical treatment and by identifying the appropriate surgeon after documenting the tumor, its operability and patient's adherence to the surgical treatment. © 2018.

Abstract
Radiotherapy is an available but not well-known treatment for management of basal cell carcinoma. National organizations have established that standard therapy is complete surgical removal and radiation therapy is an option for inoperable tumors or those where the post-operative defect would be cosmetically disfiguring or functionally disabling. These therapeutic options, with histological sample, should be considered in the multidisciplinary management of patients with basal cell carcinoma. There are several types of radiotherapy: external radiation or interstitial brachytherapy, unfortunately, there is no consensus in the literature and the range of radiation regimens in common use is large. Very few randomized studies have been conducted to defi the optimum treatment in terms of recurrence rate, cosmetic outcome and side-eff In most of studies, the overall local control rate was between 80-100% and over 90% of patients reported good or excellent cosmetic outcome. Side-eff of radiotherapy most commonly reported are minor but in young patients one must be alert to the theoretical possibility of the induction of secondary malignancies.

Abstract
The wingless/integrase-1 (WNT)/β-catenin signaling pathway is active in several chronic lung diseases including idiopathic pulmonary fibrosis, asthma, and chronic obstructive pulmonary disease. Although this WNT/β-catenin pathway activity is associated with an increase in mucus cell frequency and a decrease in ciliated cell frequency, a cause and consequence relationship between signaling and cell frequency has not been established. We previously demonstrated that genetic stabilization of β-catenin inhibited differentiation of mouse bronchiolar tissue stem cells (TSC). This study determined the effect of β-catenin and its co-factors P300 (E1A-binding protein, 300 kDa) and cAMP response element binding (CREB)-binding protein (CBP) on human bronchial epithelial TSC differentiation to mucus and ciliated cells. We developed a modified air-liquid interface (ALI) culture system in which mucus and ciliated cell frequency is similar. These cultures were treated with the β-catenin agonist CHIR99021 (CHIR) and antagonists to β-catenin (XAV939), P300 (IQ1), and CBP (ICG001). We report that human TSC differentiation to mucus and ciliated cells can be divided into two stages, specification and commitment. CHIR treatment inhibited mucus and ciliated cell commitment while XAV939 treatment demonstrated that β-catenin was necessary for mucus and ciliated cell specification. Additional studies demonstrate that a β-catenin/P300 complex promotes mucus cell specification and that β-catenin interacts with either P300 or CBP to inhibit ciliated cell commitment. These data indicate that activation of β-catenin-dependent signaling in chronic lung disease leads to changes in mucus and ciliated cell frequency and that P300 and CBP tune the β-catenin signal to favor mucus cell differentiation.

Abstract
Salivary gland neoplasms represent less than 3% of all tumors in the general population of which benign adenomas account for 65.5%. Basal cell adenoma which is classified as a subtype of monomorphic adenomas accounts for 1-2% of all salivary gland epithelial tumors, and more than 80% of them arise in the major salivary glands, mostly the parotid gland and has female predominance reporting mostly in the elderly age groups. We here report a case of basal cell adenoma of trabecular type in a male patient of age 45 years in the minor salivary glands of left posterior palatal region.

Abstract
BACKGROUND Aldehyde dehydrogenases (ALDHs) play a major role in detoxification of aldehydes. High expression of ALDHs is a marker for stem cells of many organs including the lungs. A common polymorphism in ALDH2 gene (ALDH2*2) results in inactivation of the enzyme and is associated with alcohol flushing syndrome and increased risk for cardiovascular and Alzheimer's diseases and some cancers. The effect of this ALDH2 polymorphism on the lung and its stem cells has not been thoroughly examined. METHODS We examined the association between the ALDH2*2 allele and lung function parameters in a population of healthy individuals. We also examined its association with the incidence of asthma and COPD in patient cohorts. We used the in vitro colony forming assay to detect the effect of the polymorphism on lung epithelial stem cells from both primary human surgical samples and Aldh2*2 transgenic (Tg) and Aldh2 -/- mice. Response to acute and chronic lung injuries was compared between wild type (WT), Aldh2*2 Tg and Aldh2 -/- mice. RESULTS In humans, the ALDH2*2 allele was associated with lower FEV1/FVC in the general population, but not with the development of asthma or COPD. Both the bronchial and lung epithelium carrying the ALDH2*2 allele showed a tendency for lower colony forming efficiency (CFE) compared to ALDH2 allele. In mice, the tracheal epithelial thickness, nuclear density, and number of basal stem cells were significantly lower in Aldh2 -/- and Aldh2*2 Tg adult mice than in WT. Electron microscopy showed significantly increased number of morphologically abnormal mitochondria in the trachea of Aldh2 -/- mice. Aldh2 -/- tracheal and lung cells showed higher ROS levels and fewer functional mitochondria than those from WT mice. No significant differences were detected when tracheal and lung epithelial stem cells were examined for their in vitro CFE. When exposed to chronic cigarette smoke, Aldh2*2 Tg mice were resistant to emphysema development, whereas influenza infection caused more epithelial damage in Aldh2 -/- mice than in WT mice. CONCLUSIONS ALDH2 polymorphism has several subtle effects on the lungs, some of which are similar to changes observed during normal aging, suggesting a "premature lung aging" effect.

Abstract
BACKGROUND Non-Melanoma Skin Cancer (NMSC), the most prevalent types being Squamous Cell Carcinoma (SCC) and Basal Cell Carcinoma (BCC), is the most common type of malignancy in human beings. These neoplasms are more frequent in the elderly and fair skinned people and mainly occur on sun-exposed sites of the body. Ultraviolet B (UVB) has a well-known effect in induction and promotion of growth of these cancers. The p53 tumor suppressor gene is believed to be an early target in UV-induced skin carcinogenesis. Aggregates of keratinocytes with p53 protein overexpression are frequently identified in normal human skin and are more prevalent in chronically sun-exposed skin, and have been proposed to play a role in skin cancer pathogenesis. The aim of this study was to clarify the potential role of P53 in the development of NMSC. METHODS Immunohistochemical evaluation of p53 expression in peri-lesional skin of 90 cases of SCC, BCC and melanocytic nevi was performed. RESULTS The well-delineated compact type of p53 clone, but not the strong dispersed type, was significantly more predominant in SCCs in comparison with BCCs and melanocytic nevi (P value=0.001). The size of p53 clones was also significantly greater in SCCs compared to the BCCs (P=0.003) and melanocytic nevi (P=0.001). There was no significant difference between these neoplasms regarding the frequency of P53 clones (P=0.86). CONCLUSION This study suggests the possible relationship of epidermal p53 clones with the pathogenesis of SCC.

Abstract
Cutaneous malignancies make up the majority of periocular tumors diagnosed and treated by ophthalmologists. In this review, we examine literature regarding ethnic and socioeconomic disparities in incidence and clinical outcomes of the three most common cutaneous periocular tumors: basal cell carcinoma, squamous cell carcinoma, and melanoma. In all three tumor types, the literature shows an increased incidence among two groups: those with lightly pigmented skin and those of higher socioeconomic status. While incidence is high in these groups, clinical outcomes for these patients tend to be good. Those with lower socioeconomic status and ethnic minorities, on the other hand, have a low incidence but are more likely to have poor clinical outcomes. These disparities are likely the result of both biologic and behavioral differences between patients and could provide opportunities for intervention to change risk perception and improve outcomes.

Abstract
Introduction A relatively novel application for dermoscopy is its use in the monitoring of topical treatment response for non-melanoma skin cancer. Basal cell carcinoma (BCC) is the most frequent type of skin cancer in humans. Surgical excision is still considered the “gold-standard” of treatment. However, a number of topical therapies are now available for the treatment of different types of basal cell carcinoma. Case Report This case report exemplifies the usefulness of dermoscopy in the monitoring of residual disease after incomplete surgical excision and also in the monitoring of topical treatment response. Imiquimod 5% cream acts as a topical immune response modifier promoting a Th-1 immune response enhancing the removal of neoplastic cells and has proven to reduce deregulated Hedgehog (HH)/GLI signal strength independent of Toll-like receptor signaling, which makes it a valuable adjuvant topical therapy for the treatment of basal cell carcinoma.

Abstract
The development of the lung epithelium is regulated in a stepwise fashion to generate numerous differentiated and stem cell lineages in the adult lung. How these different lineages are generated in a spatially and temporally restricted fashion remains poorly understood, although epigenetic regulation probably plays an important role. We show that the Polycomb repressive complex 2 component Ezh2 is highly expressed in early lung development but is gradually downregulated by late gestation. Deletion of Ezh2 in early lung endoderm progenitors leads to the ectopic and premature appearance of Trp63+ basal cells that extend the entire length of the airway. Loss of Ezh2 also leads to reduced secretory cell differentiation. In their place, morphologically similar cells develop that express a subset of basal cell genes, including keratin 5, but no longer express high levels of either Trp63 or of standard secretory cell markers. This suggests that Ezh2 regulates the phenotypic switch between basal cells and secretory cells. Together, these findings show that Ezh2 restricts the basal cell lineage during normal lung endoderm development to allow the proper patterning of epithelial lineages during lung formation.

Abstract
Tripartite motif protein 29 (TRIM29) is one of the TRIM family proteins, some of which function as E3 ubiquitin ligases. In this study, we investigated the usefulness of TRIM29 for diagnosis of prostate cancer. Prostate tissues including carcinoma and non-carcinoma tissues obtained by needle biopsy and radical prostatectomy were used. Immunohistochemistry was performed according to standard procedures using an antibody against TRIM29. Immunohistochemical staining with an antibody against 34βE12, which recognizes cytokeratins 1, 5, 10 and 14, was performed as a control. Basal cells of normal prostatic glands were stained with anti-TRIM29 antibody in all cases, whereas prostate cancer tissues had no or little staining with anti-TRIM29 antibody. TRIM29 is selectively expressed in basal cells of the normal prostate gland, and immunohistochemical staining with anti-TRIM29 antibody showed the same expression pattern as that with 34βE12 in prostate cancer and its benign mimics. Our data indicate that TRIM29 may be useful for distinguishing prostate cancers from benign tissues.

Abstract
Patients with small cell lung carcinoma (SCLC) rarely demonstrate long-term survival. We previously reported that gene expression profiling identified a subset of SCLC with good prognosis in surgical cases. To find an easier way to routinely identify SCLC belonging to this subset, we conducted the present study with a hypothesis that neuroendocrine (NE) or basaloid (BA) phenotypes may influence prognosis. To confirm the subset, we used an array platform to analyze fresh samples. Because inoperable cases may differ from surgical cases, we enrolled 51 biopsy cases and 43 resected samples. To evaluate NE and BA phenotypes, we used NE (synaptophysin, chromogranin A, and CD56) and BA (p63 and CK34βE12) markers. To varying extents, expression profiling based on the array platform duplicated the subsets. For NE phenotypes, 77% of surgical cases and 100% of biopsy cases were positive for at least 1 marker. For BA phenotypes, only 19% of surgical cases were positive for at least 1 marker, whereas there were no positive biopsy cases. Cases undergoing surgery were categorized based on NE and BA immunoreactivity; 58% into NE+BA-, 19% into NE+BA+, 23% into NE-BA-, and 0 into NE-BA+ groups. NE- patients (n = 10) demonstrated a significantly better prognosis (P = .0306) than their NE+ counterparts (n = 33), whereas no survival difference was evident between the BA+ and BA- groups. Multivariate analyses showed that NE positivity was an independent prognostic factor. In conclusion, the SCLC subset with good prognosis is identified by low NE marker expression, which was found only in surgical cases.
