MACS GMP Recombinant Human SHH (C24II)，170-076-182，美天旎

Recombinant Human SHH (Sonic Hedgehog; or C24II) can promote growth and differentiation of embryonic stem cells, adult mesenchymal stem cells, and cells within the neuronal lineage. The morphogenetic cytokine is crucial for embryonic development, as it is involved in the patterning of the central nervous system, somites, and limbs.

MACS GMP Recombinant Human SHH (C24II) is designed for ex vivo cell culture processing. No animal- or human-derived materials were used for the manufacture of this product, unless otherwise stated in the respective product quality certificate. The product is lyophilized without carrier protein or preservatives.

Biological activity

Sonic hedgehog (SHH) is involved in a wide variety of embryonic developmental events, including neurogenesis, limb development, hematopoiesis, and gut formation. Besides their role as morphogens, hedgehog family members have also been shown to act as mitogens, cell survival factors, and axon guidance factors and to influence tissue regeneration within the adult. SHH is synthesized as a precursor, which is autocatalytically cleaved into a 19 kDa N-terminal domain (SHH-N) and a 25 kDa C-terminal domain (SHH-C). SHH-N is responsible for the signaling activity of hedgehog proteins, while SHH-C acts as a cholesterol transferase and covalently attaches a cholesterol molecule to SHH-N. The lipid-modified SHH-N displays enhanced activity. Human SHH (C24II) corresponds to the mature SHH-N domain and carries a Cys to Ile-Ile substitution resulting in a lipophilic moiety and therefore an increased activity.

MACS GMP Recombinant Human SHH (C24II) can be used for a variety of applications including:

Expansion or differentiation of various cell types, mainly human and mouse embryonic stem cells, but also adult stem cells and mesenchymal cells. Human SHH (C24II) is an essential growth factor for the differentiation of dompaninergic progenitors from PSCs.
