Revealing developmental networks by comparative transcriptomics

Comparative cell cycle transcriptomics reveals synchronization of developmental transcription factor networks in cancer cells

The cell cycle coordinates core functions such as replication and cell division. However, cell-cycle-regulated transcription in the control of non-core functions, such as cell identity maintenance through specific transcription factors (TFs) and signalling pathways remains unclear. Here, we provide a resource consisting of mapped transcriptomes in unsynchronized HeLa and U2OS cancer cells sorte...

Comparative Transcriptomics of Alternative Developmental Phenotypes in a Marine Gastropod.

Alternative phenotypes are discrete phenotypic differences that develop in response to both genetic and environmental cues. Nutritive embryos, which arrest their development to serve as nutrition for their viable siblings, are an example of an alternative developmental phenotype found in many animal groups. Females of the marine snail, Crepidula navicella, produce broods that consist mainly of ...

Transcriptomics in developmental toxicity testing

Reproductive toxicity testing is one of the most complex, expensive and labor intensive fields of toxicology (Leist et al. drastically demonstrate the fundamental importance of reliable developmental toxicity tests for human safety (van Recently, human embryonic stem cell based in vitro test systems have been established that recapitulate critical periods of human early development (Krug et al....

Revealing New Mouse Epicardial Cell Markers through Transcriptomics

BACKGROUND The epicardium has key functions during myocardial development, by contributing to the formation of coronary endothelial and smooth muscle cells, cardiac fibroblasts, and potentially cardiomyocytes. The epicardium plays a morphogenetic role by emitting signals to promote and maintain cardiomyocyte proliferation. In a regenerative context, the adult epicardium might comprise a progeni...
