INTRODUCTION: Diabetes is known as a worldwide disease with a great burden on society. Since therapeutic options cover a limited number of target points, new therapeutic strategies in the field of regenerative medicine are considered. Bioscaffolds along with islet cells would provide bioengineered tissue as a substitute for β-cells. The perfusion-decellularization technique is considered to create such scaffolds since they mimic the compositional, architectural, and biomechanical nature of a native organ...

Immunohistochemistry for several neurochemical substances was performed on the human incisive papilla and other oral structures. Sodium channel alpha subunit 7 (SCN7A) protein-immunoreactive (IR) Schwann cells and protein gene product 9.5 (PGP 9.5)-IR nerve fibers made nerve plexuses beneath the epithelium of the palate, including the incisive papilla, tongue, and lip. SCN7A immunoreactivity could also be detected in lamellated and nonlamellated capsules of corpuscle endings. Lamellated SCN7A-IR corpuscle endings were mostly restricted to the mucous and cutaneous lips...

The vomeronasal organ (VNO) is the peripheral receptor organ of the accessory olfactory system, which is responsible for both sexual and innate behaviors. The degree of neuronal differentiation and maturation of the vomeronasal receptor cells together with the verification of the presence of the solitary chemoreceptor cells (SCCs) in the VNO of Corriedale sheep were assessed using immunofluorescence. A protein gene product 9.5 (PGP 9.5), which is a neuronal marker recognized to be expressed in most neurons of vertebrate species, an olfactory marker protein (OMP) that is precise for mature olfactory receptor cells, and lastly phospholipase C-β2 (PLC-β2), a marker in the signal transduction pathway of SCCs, were all tested...

The aim of this study was to evaluate the role of epithelial signal transducer and activator of transcription 3 (STAT3) in mouse incisor amelogenesis. Since Stat3 is expressed in the epithelial component of developing and adult mouse teeth, we generated and analyzed Krt14Cre/+;Stat3fl/fl mutant mice in which Stat3 was inactivated in epithelia including ameloblast progenitors and ameloblasts, the cells responsible for enamel formation. Histological analysis showed little enamel matrix in mutant incisors compared to controls...

The role of thecal glands in the ovary of birds remains controversial. Using transmission electron microscopy and immunohistochemistry, immunohistochemical localisation of cyclooxygenase I and II (COX-1 and COX-2), oestrogen receptor α and β (ER-α and ER-β), androgen receptor (AR) and progesterone receptor (PR), a detailed analysis of the thecal glands was performed. Our ultrastructural studies revealed that the thecal glands of the quail ovary consist of 2 cell types, steroid-producing cells (SPCs) and enclosing cells (ENCs)...

The limitation of traditional bone grafts could be overcome by applying engineered bone constructs, which are mainly produced by seeding suitable stem cells on appropriate scaffolds. So far, bone marrow-derived stromal cells have been the most applied cells in bone tissue engineering, but current data show that unrestricted somatic stem cells (USSCs) from human cord blood might actually be a better stem cell source due to the accessibility and noninvasive procedure of collection. In this study, we cultured USSCs on a plasma-treated electrospun polylactic-co-glycolic acid (PLGA) scaffold coated with nanohydroxyapatite (nHA)...

The aim of this study was to determine the developmental characteristics of podocytes in the human fetal metanephros using scanning electron microscopy, light microscopy, and transmission electron microscopy. Kidney samples of 15 human fetuses of both sexes (gestational age 10-22 weeks) were analyzed. At the S-shaped body stage, primitive podocytes were arranged in a layer of cuboidal cells beneath the vascular cleft. When observed from Bowman's space, the demarcation between adjacent podocytes was not clear, but mild depressions indicated cell boundaries...

Obesity is a potent risk factor for knee osteoarthritis (OA) that is driven by mechanical and potentially endocrine mechanisms, and it affects women more frequently than men. The infrapatellar fat pat (IPFP) represents a potential link between obesity, intra-articular inflammation and structural pathology. Here we investigate whether the IPFP is responsive to body weight loss/gain in women and how its responsiveness to weight change compares to that of subcutaneous fat (SCF) of the thigh. All female participants of the Osteoarthritis Initiative (OAI) with ≥10% weight loss/gain between baseline and a 2-year follow-up were included...

Mammalian cells, e.g., CHO, BHK, HEK293, HT-1080, and NS0 cells, represent important manufacturing platforms in bioengineering. They are widely used for the production of recombinant therapeutic proteins, vaccines, anticancer agents, and other clinically relevant drugs. HEK293 (human embryonic kidney 293) cells and their derived cell lines provide an attractive heterologous system for the development of recombinant proteins or adenovirus productions, not least due to their human-like posttranslational modification of protein molecules to provide the desired biological activity...

The combination of bone tissue scaffolds with osteogenic induction factors is an effective strategy to facilitate bone healing processes. Here, chitosan (CS)/nano-hydroxyapatite (HA) scaffolds containing simvastatin (SIM)-loaded PLGA microspheres were fabricated by combining a freeze-drying technique with a modified water-oil-water emulsion method. The CS/HA weight ratio of 1:2 was selected by analyzing the effect of HA content on the micro-architecture, mechanical strength, and biocompatibility of the scaffold...

Stable and sustainable spermatogenesis is supported by the strict regulation of self-renewal and differentiation of spermatogonial stem cells (SSC), which are a rare population of undifferentiated spermatogonia. It has been revealed that some signaling factors regulate the self-renewal of SSC; however, the molecular mechanism of SSC maintenance is still not completely understood. Notch signaling is an evolutionarily conserved juxtacrine signaling that plays important roles in the cell fate determination of various tissue stem cells...

To date, a completely in vitro repopulated tissue-engineered heart valve has not been developed. This study focused on sequentially seeding 2 cell populations onto porcine decellularized heart valve leaflets (HVL) and pericardia (PER) to obtain fully repopulated tissues. For repopulation of the interstitium, porcine valvular interstitial cells (VIC) and bone marrow-derived mesenchymal stem cells (BM-MSC) or adipose tissue-derived stem cells (ADSC) were used. In parallel, the culture medium was supplemented with ascorbic acid 2-phosphate (AA) and its effect on recolonization was investigated...

The circling mouse serves as a hearing loss model. It has spontaneous tmie gene mutations that cause hair cell and cochlear degeneration. However, little is known about the role of the tmie gene in superior olivary complex (SOC) regions, in which sound information from the two ears is integrated and primarily relayed to the nuclei of the lateral lemniscus and inferior colliculus. Several studies have reported that abnormal calcium (Ca2+) homeostasis is associated with the pathology of hearing loss. This study investigated the distribution of Ca2+-binding proteins (CaBPs), such as calbindin D28k, parvalbumin, and calretinin, in the SOC of the circling mouse on postnatal day 16...

The objective of this work was to evaluate proliferation and apoptosis in the bovine ovary in a model of follicular persistence induced by low levels of progesterone to detect incipient changes during cystic ovarian disease development on the expected day of ovulation (day 0) and after 5, 10, and 15 days of follicular persistence. We analyzed cell proliferation by evaluating the expression of Ki-67 and apoptosis by evaluating caspase-3, BAX, and BCL2 expression. Proliferation was similar in the granulosa and theca cells of antral follicles in the P0 group (treated with progesterone up to the expected day of ovulation) and in the control group...

As a result of restrictions on animal experimentation, improved skin equivalents (SEs) are needed as alternative test models. This work investigated the effects of avian collagen on the construction of SEs, and to the best of our knowledge is the first study to do so. Hematoxylin and eosin and immunohistochemical staining were used to analyze the SEs. In models containing avian collagen as a dermal equivalent (DE) ingredient, fibroblast proliferation increased by about 60% relative to the control model. Immunohistochemical staining showed that the expression of proliferating cell nuclear antigen (PCNA) and p63 increased in the avian collagen models, while the expression of involucrin, integrin α6, and integrin β1 remained unchanged...

Cartilage tissue is characterized by its poor regenerative properties, and the clinical performance of cartilage grafts to replace cartilage defects has been unsatisfactory. Recently, cartilage regeneration with mature chondrocytes and stem cells has been developed and applied in clinical settings. However, there are challenges with the use of mature chondrocytes and stem cells for tissue regeneration, including the high costs associated with the standard stem cell isolation methods and the decreased cell viability due to cell manipulation...

There are several pathologies associated with the peritoneum, such as mesothelioma and peritonitis. Moreover, the peritoneum is widely used in ultrafiltration procedures, i.e., peritoneal dialysis, presenting advantages over hemodialysis. On the other hand, ultrafiltration failure may lead to dialysis-induced fibrosis and hypervolemia. Therefore, the pathophysiological study of this tissue is of extreme biomedical importance. Studies investigating the biology of the cells dwelling in the peritoneum wall provide evidence of their plasticity and progenitor features...

Liver transplantation from deceased or living human donors remains the only proven option for patients with end-stage liver disease. However, the shortage of donor organs is a significant clinical concern that has led to the pursuit of tissue-engineered liver grafts generated from decellularized liver extracellular matrix and functional cells. Investigative efforts on optimizing both liver decellularization and recellularization protocols have been made in recent decades. In the current review, we briefly summarize these advances, including the generation of high-quality liver extracellular matrix scaffolds, evaluation criteria for quality control, modification of matrix for enhanced properties, and reseeding strategies...
