introduction: recognition of human leukocyte antigens (hla) is of importance for hematopoietic stem cell transplantation. any hla-mismatches between the donor and recipient can cause graft rejection or other complications. in hla-typing experiments, usage of hla-known reference cells accompany with hla-unknown samples is obligatory. some international centers represent these cells with high exp...

Stem cell-based therapy has been highlighted as a potential avenue to promote tissue regeneration, where stimulation of stem cells differentiate into the targeted cell type is essential. One factors that induce their surrounding microenvironment. In this study, correlation between mild reductant and early osteogenic commitment was evaluated. A surface-reducing microenvironment significantly sil...

stem cells are self-renewing cells that can be differentiated into other cell types. conventional in vitro models for studying stem cells differentiation are usually preformed in two-dimensional (2d) cultures. the design of three-dimensional (3d) in vitro models which ideally are supposed to mimic the in vivo stem cells microenvironment is potentially useful for inducing stem cell derived tissu...

Objective(s): Stem cell therapy is believed to be as a promising treatment strategy for tissue repair and regeneration. The plasticity specification of the adult stem cells, such as MSCs, has enabled that these cells to be used in the treatment of a broad spectrum of diseases like liver disorders. In this study, the production of urea and Albumin (Alb), glycogen storage, and expression of some ...

Myofiber cultures give rise to myogenic as well as to non-myogenic cells. Whether these myofiber-associated non-myogenic cells develop from resident stem cells that possess mesenchymal plasticity or from other stem cells such as mesenchymal stem cells (MSCs) remain unsolved. To address this question, we applied a method for reconstructing cell lineage trees from somatic mutations to MSCs and my...

Objective- Investigating of the isolation, culture, differentiation potential and electronic microscopic characterization of canine periodontal ligament stem cells (PDLSCs). Design- Experimental in vitro study Animals- Four intact, male, mongrel dogs, 8-10 months-old were selected to collect PDLSCs from their teeth. Procedures- The dogs were anesthetized and the first maxillary and mandibula...

BACKGROUND Chronic myeloid leukemia (CML) is a clonal myeloproliferative disorder of hematopoietic stem cells. It is characterized at the cytogenetic level by Philadelphia (ph) chromosome and at the molecular level by the BCR/ABL gene rearrangement. Bone marrow derived mesenchymal stem cells (MSCs) are pluripotent stem cells that can differentiate into several mesenchymal tissues. AIM To obse...

Objective(s): Nowadays much effort is being invested in order to diagnose the mechanisms involved in neural differentiation. By clarifying this, making desired neural cells in vitro and applying them into diverse neurological disorders suffered from neural cell malfunctions could be a feasible choice. Thus, the present study assessed the capability of fetal brain extract (FBE) to induce rat bon...
