Mesenchymal stem cells (MSCs) have been shown to exert therapeutic effects on various autoimmune diseases. However, such therapeutic effect is not always achieved. Among many reasons, MSC culture methodologies may account for the these differences. It is known that oxygen concentration could profoundly affect the properties of MSCs. Therefore, we compared human umbilical cord derived MSCs cultured under hypoxic and normoxic conditions.

View SamplesWe generated three kinds of genetically identical mouse reprogrammed cells: induced pluripotent stem cells (iPSCs), nuclear transfer embryonic stem cells (ntESCs) and iPSC-nt-ESCs that are established after successively reprogramming of iPSCs by nuclear transfer (NT). NtESCs show better developmental potential than iPSCs, whereas iPSC-nt-ESCs display worse developmental potential than iPSCs.

View SamplesThe WHV/c-myc transgenic mouse is an animal model of hepatocarcinogenesis that can exquisitely mimic the cancer staging in human Hepatocellular carcinoma (HCC), in which the c-myc oncogene is activated by adjacent woodchuck hepatitis virus (WHV) DNA sequences. Compared to other models of c-myc transgenic mice, WHV/c-myc mice stably develop HCC with a relatively short latent period of 8 to 12 months, with a high (near 100%) tumor incidence.

View SamplesHaploid pluripotent stem cells, such as haploid embryonic stem cells (haESCs), facilitate the genetic study of recessive traits. In vitro, fish haESCs maintain haploidy in both undifferentiated and differentiated states, but whether mammalian haESCs can preserve pluripotency in the haploid state has not been tested. Here, we report that mouse haESCs can differentiate in vitro into haploid epiblast stem cells (haEpiSCs), which maintain an intact haploid genome, unlimited self-renewal potential, and durable pluripotency to differentiate into various tissues in vitro and in vivo. Mechanistically, the maintenance of self-renewal potential depends on the Activin/bFGF pathway. We further show that haEpiSCs can differentiate in vitro into haploid progenitor-like cells.

View SamplesHaploid stem cells offer an easy-to-manipulate genetic system and therefore have great values for studies of recessive phenotypes. Here, we show that mouse androgenetic haploid ES (ahES) cell lines can be established by transferring sperm into enucleated oocyte. The ahES cells maintain haploidy and stable growth over 30 passages, express pluripotent markers, possess the ability to differentiate into all three germ-layers in vitro and in vivo, and contribute to germline of chimeras when injected into blastocysts. Although epigenetically distinct from sperm cells, the ahES cells can produce viable and fertile progenies after intracytoplasmic injection into mature oocytes. The oocyte injection procedure can also produce viable transgenic mice from genetically engineered ahES cells.
