Abstract:
The glycoprotein hormone stanniocalcin (STC) has originally been described in the teleost kidney. Since then, STC homologs have been identified in various genomes including human, mouse, rat, Xenopus and zebrafish. In mammals, two STC genes, STC1 and STC2, are known. We cloned a chicken STC homolog to analyze its expression pattern during chick development. Sequence analyses revealed a high sequence similarity of the chicken STC (cSTC) clone to mammalian STC2. Interestingly the expression pattern of cSTC2 largely resembles those of murine STC1: we found expression of cSTC2 in the nephric tubules, in the myocardium, in skeletal muscle cells from the onset of differentiation, and in synovial joint anlagen of the limbs.

Smooth Muscle Contraction
The onset of contraction is triggered by an increase in calcium ions within the sarcoplasm, similar to the process in striated muscle. However, smooth muscles have a relatively smaller reservoir of the sarcoplasmic...

Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
