BACKGROUND Spermatozoa acquire the ability to fertilize an oocyte when they become capacitated. Capacitation takes place when sperm pass through the female reproductive tract, interacting with female fluids. Both tyrosine phosphorylation of sperm proteins and the ability to respond to acrosome reaction (AR) inducers have been associated with sperm capacitation. Recent data indicate that conditi...

Background & Aims: One of cell- based technical issues associated with cartilage repair assay is delivering cells to the site of the parts where damage is created. Mesenchymal stem cells (MSCs) with their chondrogenic potential are ideal candidates for cartilage regeneration. High expression of cartilage hypertrophy markers by MSCs would result in apoptosis and ossification. This investigation ...

Neuroblastomas are histopathologically heterogeneous, ranging from immature malignant tumors to benign ganglioneuromas. The amount of Schwann cell stroma greatly increases with neuroblastoma differentiation, and these Schwann cells appear to be normal cells that infiltrate the tumor. To determine whether Schwann cells influence neuroblast differentiation, four human neuroblastoma cell lines wer...
