View SamplesIn mouse, spermatogonial stem/progenitor cells are the progenitor cell which develop to mature sperms through a series of mitotic and meiotic divisions and differentiation. Gfra1 is an established surface marker for mouse spermatogonial stem/progenitor cells. In this study, we used a transcriptomic approach to investigate the effect of aging on Gfra1-positive and -negative populations of mouse male germ cells.

View SamplesThe goal of this study is to investigate the molecular mechanism of lhx1 on regulation of pronephros formation during the early embryonic development. In the vertebrate embryo the kidney is derived from the intermediate mesoderm. The LIM-class homeobox transcription factor lhx1 is expressed early in the intermediate mesoderm and is one of the first genes to be expressed in the nephric mesenchyme. The animal cap cells can be induced by treatment of activin and retinoic acid to differentiate into pronephros tissue. In this study we investigated the role of Lhx1 in differentiation of pronephros by depleting lhx1 in the organ culture system. We generated the gene expression profile of early pronephros tissue, and demonstrated that expression of genes from all the kidney domains is affected by the absence of lhx1. Taken together our results highlight an essential role for Lhx1 in pronephros formation.
Lhx1 is required for specification of the renal progenitor cell field.

View SamplesWe hypothesized that preterm spontaneous labor involves aberrant changes in mRNA expression in the placenta. To test this hypothesis, we interrogated the mRNA levels of >50,000 genes and transcript variants using gene expression microarray (Human Genome U133 Plus 2.0 Array, Affymetrix) on 5 placentas collected from preterm spontaneous delivery (<34 weeks of gestation) and another 5 placentas collected from term spontaneous delivery (38-39 weeks).

View SamplesPrimitive neural stem cells (NSCs) could be derived from pluripotent mouse embryonic stem (ES) cells, and then differentiate into definitive-type neural stem cells which resemble NSCs obtained from the central nervous system. Hence, primitive NSCs define an early stage of neural induction and provide a model to understand the mechanism that controls initial neural commitment.
LIF-dependent primitive neural stem cells derived from mouse ES cells represent a reversible stage of neural commitment.

View SamplesDuring embryonic development, the neural crest is a transient, migratory cell population that differentiates into a large variety of tissues and contributes much to the formation of vertebrate body. In Xenopus, lrig3 is involved in neural crest formation by modulating FGF and Wnt signaling. Lrig3 functions downstream of pax3 and zic1 to regulate the expression of neural crest markers.
