The early cortical primordium develops from a sheet of neuroepithelium that is flanked by
distinct signaling centers. Of these, the hem and the antihem are positioned as longitudinal …

Wnt signalling plays important roles in patterning and outgrowth of the vertebrate limb.
Different mutations in Wnt genes, their antagonists or (co-) receptors result in patterning and …

We have demonstrated that mesenchymal stem cells overexpressing the survival gene Akt
can confer paracrine protection to ischemic myocytes both in vivo and in vitro through the …

Wnt factors are involved in the regulation of all steps of cartilage development. The activity of
Wnt factors is generally regulated at the extracellular level by factors like the Dkk family …

With contrasting observations on the effects of β-catenin on hematopoietic stem cells
(HSCs), the precise role of Wnt/β-catenin signals on HSC regulation remains unclear. Here …

A comprehensive expression analysis of WNT signalling pathway genes during several
stages of chicken facial development was performed. Thirty genes were surveyed including …

Background Wnt signalling regulates multiple aspects of brain development in vertebrate
embryos. A large number of Wnt s are expressed in the embryonic forebrain; however, it is …

The valves and septa of the mature heart are derived from the cardiac cushions, which
develop from discrete swellings in two regions of developing heart tube: the atrioventricular …

方法采用荧光定量PCR 法定量分析SFRPImRNA 在不同淋巴结转移能力卵巢癌Skov3 …

Background During the development of the central nervous system (CNS), patterning
processes along the dorsoventral (DV) axis of the neural tube generate different neuronal …
