Purpose: After aneuploidy,sperm premature chromatin condensation (PCC) is the next most important cause of fertilization failure. Therefore the aim of this study is to evaluate the effect of sperm protamine deficiency on sperm PCC formation post ICSI. Materials and Methods: Cytogenetic analysis was carried out on unfertilized oocytes post ICSI and incidence of sperm PCC was evaluated. The resu...
Bone-marrow mesenchymal stem cell (BM-MSC) proliferation and lineage commitment are under the coordinated control of metabolism epigenetics; MSC niche contains low oxygen, which is an important determinant cellular metabolic state. In turn, drives fate decisions via alterations chromatin landscape. Due to fundamental role BM-MSCs in development adipose tissue, bones cartilage, age-associated ch...
