Abstract
Biobased porous hydrogels enriched with phytocompounds-rich herbal extracts have aroused great interest in recent years, especially in healthcare. In this study, new macroporous hybrid cryogel constructs comprising thiourea-containing chitosan (CSTU) derivative and a Hypericum perforatum L. extract (HYPE), commonly known as St John's wort, were prepared by a facile one-pot ice-templating strategy. Benefiting from the strong interactions between the functional groups of the CSTU matrix and those of polyphenols in HYPE, the hybrid cryogels possess excellent liquid absorption capacity, mechanical resilience, antioxidant performance, and a broad spectrum of antibacterial activity simultaneously. Thus, owing to their design, the hybrid constructs exhibit an interconnected porous architecture with the ability to absorb over 33 and 136 times their dry weight, respectively, when contacted with a phosphate buffer solution (pH 7.4) and an acidic aqueous solution (pH 2). These cryogel constructs have extremely high compressive strengths ranging from 839 to 1045 kPa and withstand elevated strains of over 70% without developing fractures. Moreover, the water-swollen hybrid cryogels with the highest HYPE content revealed a complete and instant shape recovery after uniaxial compression. The incorporation of HYPE into CSTU cryogels enabled substantial improvement in scavenging reactive oxygen species and an expanded antibacterial spectrum toward multiple pathogens, including Gram-positive bacteria (Staphylococcus aureus and Staphylococcus epidermidis), Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa), and fungi (Candida albicans). Cell viability experiments demonstrated the cytocompatibility of the 3D cryogel constructs, which did not induce changes in the fibroblast morphology. This work showcases a simple and effective strategy to immobilize HYPE extracts on CSTU 3D networks, allowing the development of novel multifunctional platforms with promising potential in hemostasis, wound dressing, and dermal regeneration scaffolds.

Abstract
The rapid development of tissue engineering (TE) and regenerative medicine brings an acute need for biocompatible and bioactive biological scaffolds to regenerate or restore damaged tissue. Great attention is focused on the decellularization of tissues or even whole organs, and the subsequent colonization of such decellularized extracellular matrices by recipient cells. The foreskin is an integral, normal part of the external genitalia that forms the anatomical covering of the glans penis and the urinary meatus of all human and non-human primates. It is mucocutaneous tissue that marks the boundary between mucosa and skin. In this work, we compared two innovative decellularization techniques for human foreskins obtained from donors. We compared the efficacy and feasibility of these protocols and the biosafety of prepared acellular dermal matrixes that can serve as a suitable scaffold for TE. The present study confirms the feasibility of foreskin decellularization based on enzymatic or detergent methods. Both techniques conserved the ultrastructure and composition of natural ECM while being DNA-free and non-toxic, making it an excellent scaffold for follow-up research and TE applications.

Abstract
Chronological skin ageing is an inevitable physiological process that results in thin and sagging skin, fine wrinkles, and gradual dermal atrophy. The main therapeutic approaches to soft tissue augmentation involve using dermal fillers, where natural fillers, such as autologous fibroblasts, are involved in generating dermal matrix proteins. The aim of this study was to determine the global transcriptome profile of three passages of dermal autologous fibroblasts from a male volunteer, focusing on the processes of the cell cycle and cell proliferation status to estimate the optimal passage of the tested cells with respect to their reimplantation. We performed K-means clustering and validation of the expression of the selected mRNA by qRT-PCR. Ten genes were selected (ANLN, BUB1, CDC20, CCNA2, DLGAP5, MKI67, PLK1, PRC1, SPAG5, and TPX2) from the top five processes annotated to cluster 5. Detailed microarray analysis of the fibroblast genes indicated that the cell population of the third passage exhibited the highest number of upregulated genes involved in the cell cycle and cell proliferation. In all cases, the results of qRT-PCR confirmed the differences in expression of the selected mRNAs between fibroblasts from the primary culture (C0) and from the first (C1), second (C2), and third (C3) cell passage. Our results thus suggest that these cells might be useful for increasing fibroblast numbers after reimplantation into a recipient's skin, and the method used in this study seems to be an excellent tool for autologous transplantation allowing the rejuvenation of aging skin.

Abstract
Dermal fibroblasts are responsible from the production of extracellular matrix and take role in the closure of skin wounds. Dermal fibroblasts are major cells of origin in the generation of induced pluripotent stem cells (IPSCs) and are historically being used as feeder layer and biofiller in the restorative surgeries. ex vivo expansion of the dermal fibroblasts provides a suitable model to study skin biology and to engineer bioartifical skins. Thus, development of efficient fibroblast expansion technologies gets outmost importance day by day. We sought to identify small molecules that induce ex vivo fibroblast expansion and understand their mechanisms. We analyzed the effect of 35 small molecules, which are expected to target molecular pathways involving cellular quiescence. We have found that small molecules, especially AS1949490 and SKF96365, increase human dermal fibroblast expansion of at least three different fibroblasts. Cell cycle analysis confirms that these small molecules allow cell cycle progression, as evident by increased percentage of cells in S-G2 -M phase of cell cycle. They led to a lower profile of apoptotic or necrotic fibroblasts. Intriguingly, we have found that identified small molecules could also endogenously induce the expression of IPSC generation, collagen synthesis, and aging-related genes. Identified small molecules may contribute to the induction of collagen synthesis in the biofiller products, the development of fibroblast products with better aging profile, and the improvement of IPSC generation.

Abstract
At present, the etiology of most non-obstructive azoospermia (NOA) remains unclear. In vitro generation of patient-specific induced pluripotent stem cells (iPSCs) is an effective approach for exploring the mechanisms of human disease. Here, we established iPSCs from two patients with idiopathic NOA and differentiated them into primordial germ cell-like cells (PGCLCs) in vitro. Compared with iPSCs derived from normal fertile men, the NOA patient-specific iPSCs show decreased efficiency of PGCLC formation in vitro. Particularly, the embryoids derived from NOA patient-specific iPSCs show defects in the expression of early primordial germ cell (PGC) genes. The transcriptome analysis reveals the expression patterns of key human PGC genes are generally similar in PGCLCs differentiated from all iPSC lines, and the differentially expressed genes were enriched with gene ontology (GO) of cell cycle and apoptosis regulation. Moreover, the PGCLCs derived from NOA patient-specific iPSCs might have initiated epigenetic reprogramming at a very early stage. Thus, the NOA patient-specific iPSCs exhibit poor response to germ cell induction in vitro, which may be related to the regulation of apoptotic process. These findings provide a foundation for future research on mechanism of male infertility.

Abstract
Implantation of autologous fibroblasts is a method used to correct age-related changes in facial skin. The aim of this study was to establish the optimal population of cultured human fibroblasts according to the organization of the extracellular matrix in the dermis. Transcriptome profile analysis of cells derived from three consecutive passages indicated that fibroblasts after the second passage were the population with the greatest number of upregulated genes encoding the critical biological processes responsible for skin regeneration, such as extracellular matrix organization, collagen fibril organization, and cell adhesion. Furthermore, genes encoding proteinases responsible for the degradation of dermal extracellular matrix proteins were noticeably downregulated at this stage of culture. Autologous fibroblasts seem to be an optimal and safe biological filler for the renewal of all skin structures.

Abstract
The skin, as the largest organ of the human body, is an important source of stromal stem cells with multipotent differentiation potential. CD105+ mesenchymal stem cells exhibit a higher level of stemness than CD105− cells. In the present study, human dermal-derived CD105+ fibroblast cells (CD105+ hDDFCs) were isolated from human foreskin specimens using immunomagnetic isolation methods to examine the role of bone morphogenetic protein (BMP)-7 in osteogenic differentiation. Adenovirus-mediated recombinant BMP7 expression enhanced osteogenesis-associated gene expression, calcium deposition, and alkaline phosphatase activity. Investigation of the underlying mechanisms showed that BMP7 activated small mothers against decapentaplegic (Smad) and p38/mitogen-activated protein kinase signaling in CD105+ hDDFCs. The small interfering RNA-mediated knockdown of Smad4 or inhibition of p38 attenuated the BMP7-induced enhancement of osteogenic differentiation. In an in vivo ectopic bone formation model, the adenovirus-mediated overexpression of BMP7 enhanced bone formation from CD105+ hDDFCs. Taken together, these data indicated that adenoviral BMP7 gene transfer in CD105+ hDDFCs may be developed as an effective tool for bone tissue engineering.

Abstract
Fibroblasts are the effector cells of fibrosis characteristic of systemic sclerosis (SSc, scleroderma) and other fibrosing conditions. The excess production of extracellular matrix (ECM) proteins is the hallmark of fibrosis in different organs, such as skin and lung. Experiments designed to assess the pro-fibrotic capacity of factors, their signaling pathways, and potential inhibitors of their effects that are conducted in fibroblasts have paved the way for planning clinical trials in SSc. As such, fibroblasts have proven to be valuable tools in the search for effective anti-fibrotic therapies for fibrosis. Herein we highlight the characteristics of fibroblasts, their role in the etiology of fibrosis, utility in experimental assays, and contribution to drug development and clinical trials in SSc.
