Identification and characterization of genes differentially expressed in X and Y sperm using suppression subtractive hybridization and cDNA microarray.

abstract：:The use of unrestricted somatic stem cells (USSCs) holds great promise for future clinical applications. Conventionally, mouse embryonic fibroblasts (MEFs) or other animal-based feeder layers are used to support embryonic stem cell (ESC) growth; the use of such feeder cells increases the risk of retroviral and other p...
