Abstract
Orofacial clefts (OFCs) are the most frequent craniofacial birth defects. An orofacial cleft (OFC) occurs as a result of deviations in palatogenesis. Cell proliferation, differentiation, adhesion, migration and apoptosis are crucial in palatogenesis. We hypothesized that deregulation of these processes in oral keratinocytes contributes to OFC. We performed microarray expression analysis on palatal keratinocytes from OFC and non-OFC individuals. Principal component analysis showed a clear difference in gene expression with 24% and 17% for the first and second component, respectively. In OFC cells, 228 genes were differentially expressed (p < 0.001). Gene ontology analysis showed enrichment of genes involved in β1 integrin-mediated adhesion and migration, as well as in P-cadherin expression. A scratch assay demonstrated reduced migration of OFC keratinocytes (343.6 ± 29.62 μm) vs. non-OFC keratinocytes (503.4 ± 41.81 μm, p < 0.05). Our results indicate that adhesion and migration are deregulated in OFC keratinocytes, which might contribute to OFC pathogenesis.

Abstract
Background The role of microRNAs (miRNAs) in animal models of palatogenesis has been shown, but only limited research has been carried out in humans. To date, no miRNA expression study on tissues or cells from cleft palate patients has been published. We compared miRNA expression in palatal fibroblasts from cleft palate patients and age-matched controls. Material and Methods Cultured palatal fibroblasts from 10 non-syndromic cleft lip and palate patients (nsCLP; mean age: 18 ± 2 months), 5 non-syndromic cleft palate only patients (nsCPO; mean age: 17 ± 2 months), and 10 controls (mean age: 24 ± 5 months) were analysed with next-generation small RNA sequencing. All subjects are from Western European descent. Sequence reads were bioinformatically processed and the differentially expressed miRNAs were technically validated using quantitative reverse-transcription polymerase chain reaction (RT-qPCR). Results Using RNA sequencing, three miRNAs (hsa-miR-93-5p, hsa-miR-18a-5p, and hsa-miR-92a-3p) were up-regulated and six (hsa-miR-29c-5p, hsa-miR-549a, hsa-miR-3182, hsa-miR-181a-5p, hsa-miR-451a, and hsa-miR-92b-5p) were down-regulated in nsCPO fibroblasts. One miRNA (hsa-miR-505-3p) was down-regulated in nsCLP fibroblasts. Of these, hsa-miR-505-3p, hsa-miR-92a, hsa-miR-181a, and hsa-miR-451a were also differentially expressed using RT-PCR with a higher fold change than in RNAseq. Limitations The small sample size may limit the value of the data. In addition, interpretation of the data is complicated by the fact that biopsy samples are taken after birth, while the origin of the cleft lies in the embryonic period. This, together with possible effects of the culture medium, implies that only cell-autonomous genetic and epigenetic differences might be detected. Conclusions For the first time, we have shown that several miRNAs appear to be dysregulated in palatal fibroblasts from patients with nsCLP and nsCPO. Furthermore, large-scale genomic and expression studies are needed to validate these findings.

Abstract
Cleft lip palate is a human congenital disorder worldwide and the study of this genetic disease requires molecular genetic analysis. This analysis required the use of nucleic acid and protein, thus good quality and quantity of its extraction is important. We are comparing RNA and protein extractions from tissue biopsy of cleft lip palate in both fresh and stabilized condition. Tissue morphology was also captured using Scanning Electron Microscopy (SEM) for any morphology differences. Tissue homogenization may destroy nucleic acid stability but not its morphology. Low RNA concentration from stabilized tissue was found. However, there was no crucial issue of protein extraction, degradation or concentration. Tissue morphology was slight different between normal and CL/P tissue.

Abstract
Organotypic epithelial structures can be cultured using primary or immortalized keratinocytes. However, there has been little detailed quantitative histological characterization of such cultures in comparison with normal mucosal architecture. The aim of this study is to identify morphological markers of tissue architecture that can be used to monitor tissue structure, maturation, and differentiation and to enable quantitative comparison of organotypic cultures (OCs) with normal oral mucosa. OCs of oral keratinocytes [immortalized H400 or primary rat keratinocytes (PRKs)] were generated using the three scaffolds of de-epidermalized dermis (DED), polyethylene terephthalate (PET), and collagen gels for up to 14 days. Cultures and normal epithelium were analyzed immunohistochemically and by using the semi-quantitative reverse transcriptase polymerase chain reaction (sq-RT-PCR) for E-cadherin, desmoglein-3, plakophilin, involucrin, cytokeratins-1, -5, -6, -10, -13, and Ki67. The epithelial thickness of OCs was measured in stained sections using image processing. Histological analysis revealed that air-liquid interface (ALI) cultures generated stratified organotypic epithelial structures by 14-days. The final thickness of these cultures as well as the degree of maturation/stratification (including stratum corneum formation) varied significantly depending on the scaffold used. For certain scaffolds, the immunohistochemical profiles obtained recapitulated those of normal oral epithelium indicating comparable in vitro differentiation and proliferation. In conclusion, quantitative microscopy approaches enabled unbiased architectural characterization of OCs. The scaffold materials used in the present study (DED, collagen type-I and PET) differentially influenced cell behavior in OCs of oral epithelia. H400 and PRK OCs on DED at the ALI demonstrated similar characteristics in terms of gene expression and protein distribution to the normal tissue architecture.

Abstract
OBJECTIVES To investigate salivary proteins with proteomic technologies to evaluate protein composition differences between samples with cleft lip and palate and healthy controls. DESIGN, PARTICIPANTS Matrix-assisted laser desorption/ionization tandem time-of-flight (MALDI TOF/TOF) mass spectrometry was used as a high-throughput analytical technique for identification of nonsyndromic cleft lip and palate stimulated salivary proteins. The samples consisted of two groups: 31 cleft lip and palate patients and a control group with 20 healthy volunteers. RESULTS The presence of cleft lip and palate stimulated the expression of several proteins, included adaptor-related protein complex 3, dermokine, nidogen 1 precursor, transforming growth factor-β3, and a zinc finger RAN-binding domain containing 2. CONCLUSIONS The salivary proteome of cleft lip and palate patients differs from the protein composition of healthy control saliva samples. Several common secreted proteins such as actins, salivary cystatins, and keratins were upregulated by cleft; increased levels of TGF-β3 and dermokine were detected in the pathologic samples. The current proteomic results suggest keratinocyte activation among patients with cleft lip and palate. The score of our preliminary results suggests the hypothesis that identified salivary proteins are of vital clinical importance in tissue regeneration and the molecular repair mechanism seen in patients with cleft lip and palate.

Abstract
Oral mucosa consists of two tissue layers, the superficial epithelium and the underlying lamina propria. Together, oral mucosa functions as a barrier against exogenous substances and pathogens. In development, interactions of stem/progenitor cells of the epithelium and mesenchyme are crucial to the morphogenesis of oral mucosa. Previous work in oral mucosa regeneration has yielded important clues for several meritorious proof-of-concept approaches. Tissue engineering offers a broad array of novel tools for oral mucosa regeneration with reduced donor site trauma and accelerated clinical translation. However, the developmental concept of epithelial-mesenchymal interactions (EMIs) is rarely considered in oral mucosa regeneration. EMIs in postnatal oral mucosa regeneration likely will not be a simple recapitulation of prenatal oral mucosa development. Biomaterial scaffolds play an indispensible role for oral mucosa regeneration and should provide a conducive environment for pivotal EMIs. Autocrine and paracrine factors, either exogenously delivered or innately produced, have rarely been and should be harnessed to promote oral mucosa regeneration. This review focuses on a working concept of epithelial and mesenchymal interactions in oral mucosa regeneration.

Abstract
Clinical application of tissue engineered palatal mucosa is hampered by unavailability of suitable oral keratinocytes as seeding cells. The aim of this study is to fabricate a tissue engineered palatal mucosa equivalent from the oral keratinocytes which cultured from cryopreserved lip mucosa tissues. Abundant lip mucosa tissues during cheilorrhaphy were firstly cryopreserved in liquid nitrogen for four to six months, and then recovered to culture oral keratinocytes for the fabrication of oral mucosa equivalent. In the control groups, oral keratinocytes cultured from fresh lip mucosa, fresh palate mucosa, and cryopreserved palate mucosa were used to fabricate oral mucosa equivalents. Attachment rate of the oral keratinocytes derived from cryopreserved lip mucosa was lower than that of the keratinocytes from fresh lip mucosa samples, however, the cell cycle distribution of oral keratinocytes cultured from all four groups of mucosa samples were similar. Histologically, the fabricated mucosa equivalents from these four groups had four- to six epithelial layers, the basal cells were cubic and the outmost cells were flatten with narrow nuclei which paralleled to the surface of the dermal matrix. Additionally, Ki-67 positive stained cells were mainly located in the basal layer of the epithelium of these equivalents. These characteristics disclosed that the oral mucosa equivalent cultured from the cryopreserved lip mucosa tissue was not different with the equivalents from other groups and similar to the native palate mucosa tissue. It suggested that the cryopreserved lip mucosa tissues could be used for the construction of palatal mucosal equivalent for clinical application.
