Expression of NK-2 class homeobox gene Nkx2-6 in foregut endoderm and heart.

abstract：:Hsp47 is a heat-shock protein which interacts with newly synthesize procollagen chains in the endoplasmic reticulum (ER) of collagen-secreting cells and is thought to assist in procollagen triple helix assembly and subsequent transport to the cis-Golgi. This is supported by studies which have reported that genes encod...
