A novel multifunctional chitosan-gelatin/carboxymethyl cellulose-alginate bilayer hydrogel containing human placenta extract for accelerating full-thickness wound healing. Int J Biol Macromol 2023; 253:126929. [PMID: 37717877 DOI: 10.1016/j.ijbiomac.2023.126929] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 09/02/2023] [Accepted: 09/14/2023] [Indexed: 09/19/2023]
Abstract
The replication of skin's dermal and epidermal morphology within a full-thickness wound using a bi-layer hydrogel to cater to their distinct needs is a compelling pursuit. Moreover, human placenta extract (HPE), containing a diverse array of bioactive agents, has proven to be effective in promoting the wound healing process and enhancing epidermal keratinocytes. This study presents a multifunctional bi-layer hydrogel incorporating HPE for accelerating full-thickness wound healing through sustained HPE release, inhibition of bacteria invasion, and promotion of cell proliferation. The upper layer of the scaffold, known as the dressing layer, is composed of carboxymethyl cellulose and sodium alginate, serving as a supportive layer for cell proliferation. The under layer, referred to as the regenerative layer, is composed of chitosan and gelatin, providing an extracellular matrix-like, porous, moist, and antibacterial environment for cell growth. The scaffold was optimized to replicate the morphology of the dermal and epidermal layers, with suitable fibroblast infiltration and a pore size of approximately 283μm. Furthermore, the degradation rate of the samples matched the wound healing rate and persisted throughout this period. The sustained HPE release rate, facilitated by the degradation rate, was optimized to reach ~98% after 28 days, covering the entire healing period. The samples demonstrated robust antibacterial capabilities, with bacterial inhibition zone diameters of and 2.63±0.12cm for S. aureus and E. coli, respectively. The biocompatibility of the samples remained at approximately 68.33±4.5% after 21 days of fibroblast cell culture. The in vivo experiment indicated that the HPE@Bilayer hydrogel promotes the formation of new blood vessels and fibroblasts during the early stages of healing, leading to the appropriate formation of granulation tissue and a wound contraction rate of (79.31±3.1)%. Additionally, it resulted in the formation of a thick epidermal layer (keratinization) that effectively covered all the impaired areas, achieving a wound contraction rate of 95.83±6.3% at the late stage of wound healing. Furthermore, immunohistochemistry staining for CD31 and TGF-β revealed that the HPE@Bilayer group had 22 blood vessels/field and 34%-66% immunoactive cells, respectively, after 14 days of healing. However, by day 21, angiogenesis and TGF-β expression had declined, demonstrating that the wounds had been successfully treated with minimal scarring.

Abstract
This study was conducted to evaluate the efficacy and safety of Unicenta in female subjects with menopausal symptoms by analyzing the changes in the Kupperman index (primary endpoint) and hormonal changes (secondary endpoint). It was a randomized, multi-center, double-blind, parallel, non-inferiority clinical study conducted at two different tertiary medical centers. A Unicenta injection was shown to be non-inferior to Melsmon based on the Kupperman index in both the intent-to-treat and per-protocol populations (p = 0.789 and p = 0.826, respectively). Additionally, there were no statistically significant differences in hormone levels (estradiol, follicular-stimulating hormone) or in the evaluation of facial flushes. There was no statistically significant difference in the incidence rate of adverse events between the two groups (p = 0.505). The study demonstrated that Unicenta is not inferior to Melsmon in terms of the change in the Kupperman index after 12 days of injection. The efficacy and safety of Unicenta were shown, resulting in the improvement of menopausal symptoms.

[PMID: 36338608 PMCID: PMC9634366 DOI: 10.1016/j.imr.2022.100891] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 09/29/2022] [Accepted: 10/06/2022] [Indexed: 11/05/2022] Open
Abstract
Background Hominis placenta pharmacopuncture is widely used for climacteric symptoms. This study examined the efficacy and safety of pharmacopuncture with PLC (the extract of Hominis placenta) on hot flashes for perimenopausal and postmenopausal women. Methods This study was a randomized placebo-controlled single-blind trial, which recruited 128 perimenopausal and postmenopausal women, randomly assigned to receive pharmacopuncture with PLC or normal saline (NS) for eight weeks. The primary outcome was the mean changes in the hot flash score (HFS) and the secondary outcomes were the mean changes in the Menopause Rating Scale (MRS), follicle-stimulating hormone (FSH) levels, and estradiol (E2) levels from baseline to eight weeks. Missing values were imputed using the last-observation-carried-forward method. Results After treatment (week 9), the HFS decreased significantly in both groups (p = 0.000). The residual HFS was 47.09 ± 41.39% and 56.45 ± 44.92 % in the PLC and control groups, respectively (p = 0.262). One month after the treatment (week 13), the score of the PLC group was reduced, but the score increased in the control group (p = 0.077). There were no statistically significant differences in the mean changes in MRS, FSH, and E2 between the two groups. No serious adverse events related to this trial were noted. Conclusion In this study, Hominis placenta extract pharmacopuncture did not differ significantly from NS in reducing the hot flash score. While this therapy appears safe, the potential for long-term effect of PLC extract needs to be examined in a large randomized controlled trial with appropriate controls.

Abstract
As skin aging is one of the most common dermatological concerns in recent years, scientific research has promoted treatment strategies aimed at preventing or reversing skin aging. Breakdown of the extracellular matrix (ECM), such as collagen and elastin fibers, in the skin results in decreased skin elasticity and tension. Cutaneous cells, especially fibroblasts in the dermis layer of the skin, mainly produce ECM proteins. Although clinical studies have demonstrated that placental extract (PE) has positive effects on skin health, the molecular mechanisms by which PE acts against skin aging are still largely unknown. In this study, we performed RNA-sequence analysis to investigate whether human PE (HPE) alters ECM-related gene expression in normal human dermal fibroblast (NHDF) cells. Gene ontology analysis showed that genes related to extracellular matrix/structure organization, such as COL1A1, COL5A3, ELN, and HAS2 were highly enriched, and most of these genes were upregulated. We further confirmed that the HPE increased the type I collagen, proteoglycan versican, elastin, and hyaluronan levels in NHDF cells. Our results demonstrate that HPE activates global ECM-related gene expression in NHDF cells, which accounts for the clinical evidence that the HPE affects skin aging.

Abstract
The COVID-19 pandemic has caused unprecedented health, social, and economic crises worldwide. However, to date, there is an only a limited effective treatment for this disease. Human placenta hydrolysate (hPH) has previously been shown to be safe and to improve the health condition in patients with hyperferritinemia and COVID-19. In this study, we aimed to determine the antiviral effects of hPH against SARS-CoV-2 in vitro and in vivo models and compared with Remdesivir, an FDA-approved drug for COVID-19 treatment. To assess whether hPH inhibited SARS-CoV-2 replication, we determined the CC50, EC50, and selective index (SI) in Vero cells by infection with a SARS-CoV-2 at an MOI of 0.01. Further, groups of ferrets infected with 105.8 TCID50/ml of SARS-CoV-2 and treated with hPH at 2, 4, 6 dpi, and compared their clinical manifestation and virus titers in respiratory tracts with PBS control-treated group. The mRNA expression of immune-related cytokines was determined by qRT-PCR. hPH treatment attenuated virus replication in a dose-dependent manner in vitro. In a ferret infection study, treatment with hPH resulted in minimal bodyweight loss and attenuated virus replication in the nasal wash, turbinates, and lungs of infected ferrets. In addition, qRT-PCR results revealed that the hPH treatment remarkably upregulated the gene expression of type I (IFN-α and IFN-β) and II (IFN-γ) IFNs in SARS-CoV-2 infected ferrets. Our data collectively suggest that hPH has antiviral efficacy against SARS-CoV-2 and might be a promising therapeutic agent for the treatment of SARS-CoV-2 infection.

Abstract
Background As a large capillary network, the human placenta plays an important role throughout pregnancy. Placental vascular development is complex and delicate and involves many types of placental cells, such as trophoblasts, and mesenchymal stem cells. There has been no systematic, comparative study on the roles of these two groups of placental cells and the whole placental tissue in the placental angiogenesis. In this study, primary cytotrophoblasts (CTBs) from early pregnancy and primary human placenta-derived mesenchymal stem cells (hPDMSCs) from different stages of pregnancy were selected as the cell research objects, and full-term placental tissue was selected as the tissue research object to detect the effects of their conditioned medium (CM) on human umbilical vein endothelial cell (HUVEC) angiogenesis. Methods We successfully isolated primary hPDMSCs and CTBs, collected CM from these placental cells and sub-cultured placental tissue, and then evaluated the effects of the CM on a series of angiogenic processes in HUVECs in vitro. Furthermore, we measured the levels of angiogenic factors in the CM of placental cells or tissue by an angiogenesis antibody array. Results The results showed that not only placental cells but also sub-cultured placental tissue, to some extent, promoted HUVEC angiogenesis in vitro by promoting proliferation, adhesion, migration, invasion, and tube formation. We also found that primary placental cells in early pregnancy, whether CTBs or hPDMSCs, played more significant roles than those in full-term pregnancy. Placental cell-derived CM collected at 24 h or 48 h had the best effect, and sub-cultured placental tissue-derived CM collected at 7 days had the best effect among all the different time points. The semiquantitative angiogenesis antibody array showed that 18 of the 43 angiogenic factors had obvious spots in placental cell-derived CM or sub-cultured placental tissue-derived CM, and the levels of 5 factors (including CXCL-5, GRO, IL-6, IL-8, and MCP-1) were the highest in sub-cultured placental tissue-derived CM. Conclusions CM obtained from placental cells (primary CTBs or hPDMSCs) or sub-cultured placental tissue contained proangiogenic factors and promoted HUVEC angiogenesis in vitro. Therefore, our research is helpful to better understand placental angiogenesis regulation and provides theoretical support for the clinical application of placental components, especially sub-cultured placental tissue-derived CM, in vascular tissue engineering and clinical treatments.

Abstract
Placental structures, capable to persist in a genetically foreign organism, are a natural model of allogeneic engraftment carrying a number of distinctive properties. In this review, the main features of the placenta and its derivatives such as structure, cellular composition, immunological and endocrine aspects, and the ability to invasion and deportation are discussed. These features are considered from a perspective that determines the placental material as a unique source for regenerative cell therapies and a lesson for immunological tolerance. A historical overview of clinical applications of placental extracts, cells, and tissue components is described. Empirically accumulated data are summarized and compared with modern research. Furthermore, we define scopes and outlooks of application of placental cells and tissues in the rapidly progressing field of regenerative medicine.

Abstract
BACKGROUND The biological activities claimed for placental extract (PE) in its medical and cosmetic applications are largely assumed to be the combined effects of its various signaling molecules and nutritional constituents. But there are considerable uncertainties about this assumption. AIMS To determine the specific biological activity of PE at a molecular level. METHODS Fibroblast growth factor (FGF) activity was assessed based on the ability to induce proliferation of FGF receptor (FGFR)-overexpressing BaF3 cells. RESULTS Porcine PE (PPE), an ingredient in numerous cosmetics, activated proliferation of BaF3 cells overexpressing FGFR subtypes 1c, 2c, 2b, 3c, or 4, that is, all the major FGFR subtypes. The effect was suppressed largely or partially when the cells were treated with a FGFR inhibitor PD173074, and the FGFR-negative BaF3 parent cells exhibited minimal growth promotion as compared to the FGFR-expressing BaF3 cells. The high (>10 kDa) and low (<3 kDa) molecular weight fractions of PPE were effective activators of FGFR signaling. PPE was found to contain sulfated glycosaminoglycans, including heparin/heparan sulfate and chondroitin sulfate, which serve as both structural stabilizers of FGFs and indispensable cofactors for FGF-FGFR signaling. CONCLUSIONS These results indicate that PPE is capable of evoking FGF signaling in cells via FGFRs. Given that recombinant FGFs have proven useful for medical/cosmetic purposes, our results suggest that the medical/cosmetic utility of PPE is provided at least partly through the activation of FGF signaling in epidermal, dermal, and subdermal tissues.

Abstract
Local injections of corticosteroids or human placental extracts are sometimes used for the treatment of resistant tendinitis or fasciitis. We report a case of infectious Achilles tendinitis complicated by calcaneal osteomyelitis after injection of human placental extracts for the Achilles tendinitis. She was treated with excision of the infected bone and tendon, followed by V-Y lengthening of the proximal portion of the Achilles tendon in a single stage. At 2 years postoperative, she remained symptom free without any signs of recurrence, and the follow-up magnetic resonance imaging scan demonstrated a well-maintained Achilles tendon with normal signal intensity.

Abstract
Few rejuvenation and antiaging markers are used to evaluate food supplements. We measured three markers in peripheral blood to evaluate the antiaging effects of a food supplement containing placental extract. Samples were evaluated for CD34+ cells, insulin-like growth factor 1 (IGF1), and telomerase activity, which are all markers related to aging. To control the quality of this food supplement, five active components were monitored. In total, we examined 44 individuals who took the food supplement from 1.2 months to 23 months; the average number of CD34+ cells was almost 6-fold higher in the experimental group compared with the control group. Food supplement intake did not change serum IGF1 levels significantly. Finally, the average telomerase activity was 30% higher in the subjects taking this food supplement. In summary, our results suggest that the placental extract in the food supplement might contribute to rejuvenation and antiaging.

Abstract
Objectives. Human placental extract (HPE) has begun to be used in Korea in various ways to improve health, even though evidence-based data is insufficient. This study investigated the effects of HPE on health status in elderly Koreans. Design. Randomized, single-blind, and case-control study design. Setting and Participants. Thirty-nine community-dwelling healthy Koreans ≥65 years of age. Intervention. The participants were randomly categorized into a placebo group (n = 17) and HPE group (n = 22). The HPE group received abdominal subcutaneous injections of HPE for 8 weeks. The placebo group was injected with normal saline. Measurements. The degree of health status was surveyed by the Korean health status measure for the elderly (KoHSME V1.0) at baseline and the end of the study. Results. In the HPE group, the scores of physical function, sexual life, and general heath perception at the end of the study period were significantly improved from baseline (P = .007, .020, and .005, resp.), while the health status of the placebo group remained unchanged during the study period. There was a significant difference over the study period between the two groups in the mean change of the physical function score (P = .036). Conclusion. A HPE injection regimen can improve the health status in elderly Koreans.
