| Abstract The very low-density lipoprotein receptor (VLDLR) transports egg yolk precursors into oocytes. However, our knowledge of the distribution patterns of VLDLR variants among breeds and their relationship to egg production is still incomplete. In this study, eight single nucleotide polymorphisms (SNPs) that account for 87% of all VLDLR variants were genotyped in Nick Chick (NC, n=91), Lohmann Brown (LohB, n=50) and Lueyang (LY, n=381) chickens, the latter being an Chinese indigenous breed. Egg production by NC and LY chickens was recorded from 17 to 50 weeks. Only four similar haplotypes were found in NC and LohB, of which two accounted for 100% of all NC haplotypes and 92.5% of LohB haplotypes. In contrast, there was considerable haplotypic diversity... |

| ABSTRACT Spermatogonial stem cells (SSCs) are the foundation of spermatogenesis, during which unlimited spermatozoa is produced daily derived from SSCs in the testis throughout life of the male. Germline stem (GS) cells can be isolated from spermatogonia, which shared the characteristics of SSCs and embryonic stem cells (ESCs), and can be passaged stably in vitro. The study of GS cells contributes to understanding spermatogenesis process. However, little is known about the GS cells in domestic animals. Here, we report the successful establishment of a serum- and feeder-free system for multipotent male GS cells (mGSCs) from postnatal porcine testis. These cells expressed pluripotent markers, such as Oct4, Nanog, C-myc, and germline-specific markers... |
