Introduction: A successful society depends on coherent and successful families and it comes true when the choice of couples is made on knowledge. Marriage is a complex and delicate relationship between two human beings that plays an essential role in achieving the emotional, psychological, and physical needs of men and women; Therefore, the present study was to investigate the effectiveness of ...
background: bone marrow has recently been recognized as a novel source of stem cells for the treatment of wide range of diseases. a number of studies on murine bone marrow have shown a homogenous population of rare stage-specific embryonic antigen 1 (ssea-1) positive cells that express markers of pluripotent stem cells. this study focuses on ssea-1 positive cells isolated from murine bone marro...
Backgrond&Objective: The ability of mesenchymalstem cells (MSCs) differentiation into many cell types, as well as their ex vivo expansion potential, makes them as an attractive therapeutic tool for cell transplantation and tissue engineering. This project was designed to improve isolation culture and characterization of human amniotic membran-derivedMSSCS and human warton ,s jelly- derived MSCs...
Objective- To evaluate growth characteristics and differentiation capacity of equine mesenchymal stem cell (eMSCs) derived from bone marrow (BM). Study design- In vitro experimental study. Animals- Four young adult horses (2-5 years old) Procedure- Cell morphology and growth characteristics of eMSCs harvested from BM were evaluated in standard culture conditions. eMSCs in passage 3 were subj...
background: while articular chondrocytes are among those appropriate candidates for cartilage regeneration, the cell dedifferentiation during monolayer culture has limited their application. several investigations have indicated the usefulness of alginate, but the topic of proliferation and differentiation of chondrocytes in alginate culture has still remained controversial. methods: rat articu...
Patterns of isolation-by-distance (IBD) arise when population differentiation increases with increasing geographic distances. Patterns of IBD are usually caused by local spatial dispersal, which explains why differences of allele frequencies between populations accumulate with distance. However, spatial variations of demographic parameters such as migration rate or population density can genera...
Moroccan goats are characterized by the presence of different populations identified only based on their phenotypes. The objectives of this study were to assess the genetic differentiation of the Draa goat breed and to analyze its genetic structure and its relationships with other local populations using 12 microsatellite markers. The screening was done in South Eastern and Southern Morocco on ...
Several characteristics of habitats of herbivores and their food-plant communities, such as plant-species composition and plant quality, influence population genetics of both herbivores and their host plants. We investigated how different ecological and geographic factors affect genetic variation in and differentiation of 23 populations of the oligophagous seed predator Lygaeus equestris (Heter...
