Considerable interest has been expressed in recent years in the relative effects of different methods of DNA isolation on the physical, chemical, and biological properties of the material isolated. In particular, interest has been centered on methods of disrupting cells. Of these methods, mechanical abrasion, sonication, and chemical lysis have been most often reported. The effectiveness of mec...

Background: Doxorubicin (DOX)-induced cardiotoxicity appears to be a growing concern for extensive use in acute lymphoblastic leukemia (ALL). The new combination treatment strategies, therefore might be an effective way of decreasing its side effects as well as improving efficacy. AMG232 (KRT-232) is a potential MDM-2 inhibitor, increasing available p53 through disturbing p53-MDM-2 interaction....

Human embryonic stem (ES) cells are undifferentiated pluripotent cells derived from the inner cell mass of blastocyst stage embryos. These unique cell lines have the potential to form virtually any cell type in the body and can be propagated in vitro indefinitely in an undifferentiated state. These cells are capable of forming embryoid bodies (EB) that contain cells from all three embryonic lin...

Objective-  In the present study we investigated the isolation protocol, population doubling time (PDT) and the expression of a pluripotential gene by RT-PCR analysis of early transcription factor Nanog in caprine umbilical cord (CUC) Wharton's jelly mesenchymal cells (WJMCs). Design- Experimental in vitro study.   Animals- Four mix breed goat.   Procedures- CUCs were collected from abattoi...

Background: Toll-like receptors (TLRs) constitute a major part of innate immunity, which can distinguish pathogen associate molecular pattern. Sertoli cells create a special immunological niche that protects somniferous tubules from auto antigens and pathogens. These cells are the only somatic cells in somniferous that protect testis cells against pathogens. The purpose of this study was to eva...

Natural killer (NK) cells play a crucial role in regulating immune functions. Few studies have characterized canine NK cells. We previously demonstrated that canine peripheral blood lymphocytes (PBLs) with a low surface CD5 density (CD5lo) are considered a critical NK population. Natural killer cells in most mammals do not express T-cell markers, but canine CD5lo cells express surface molecules...
