BMP-8 is a pleiotropic ligand protein act as a reproductive system regulator, enriched in the ovary. BMP-8 is encoded by a pair of genes BMP8A and BMP8B, belonging to TNF-β family [1] . BMP-8A activates the SMAD1/5/8 and the SMAD2/3 pathways in granulosa cells, to inhibit gonadotropin-induced progesterone production and steroidogenesis-related gene expression [1] . BMP-8A also involves in Nrf2 phosphorylation in cancer cells to promote survival and drug resistance [2] . BMP-8a Protein, Human is 402 a.a. with 2 glycosylation domains. Animal-Free BMP-8a Protein, Human (His) is a animal free recombinant human protein produced in E. coli cells, with 139 a.a. (A264-H402) and C-terminal His-tag.This product is for cell culture use only.

BMP-8 is a pleiotropic ligand protein act as a reproductive system regulator. BMP-8 is encoded by a pair of genes, BMP8A and BMP8B, belonging to TNF-β family. GMP-8 initiates the canonical BMP signaling cascade by associating with type I receptor BMPR1A and type II receptor BMPR2. Both BMP8A and BMP8B are enriched in the ovary and activate canonical BMP signaling in different cells, including spermatogonia, P19 and 293T cells [1] . BMP-8 is widely found in different animals, while the sequences of BMP-8A and BMP-8B in human are highly different from Mouse with similarities of 85.96% and 74.44%, respectively. As for BMP8A, which is mainly secreted by granulosa cells within growing ovarian follicles. BMP8A encodes a secreted ligand of the TGF-β superfamily of proteins to bind various TGF-beta receptors, leading to recruitment and activation of SMAD family transcription factors and regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer [2] . BMP-8A protein activates the SMAD1/5/8 and the SMAD2/3 pathways in granulosa cells, to inhibit gonadotropin-induced progesterone production and steroidogenesis-related gene expression [1] . BMP8A protein plays a role in development of the reproductive system by sustaining spermatogenesis by activating both SMAD1/5/9 and SMAD2/3 in spermatogonia. BMP-8A protein also activates Nrf2 and Wnt pathways in clear cell renal cell carcinoma (ccRCC) to promote cell proliferation and inhibit apoptosis [2] . As for BMP8B, which protein is secreted by brown/beige adipocytes and enhances energy dissipation, serves as an interconnected regulator of neuro-vascular remodeling in AT and is potential targets in obesity [3] . BMP8B increases brown adipose tissue thermogenesis through both central and peripheral actions [4] . Thus BMP8B contributes to adrenergic-induced remodeling of the neuro-vascular network in adipose tissue, therefore through the adipocytes to 1) secrete neuregulin-4 (NRG4), which promotes sympathetic axon growth and branching in vitro, and 2) induce a pro-angiogenic transcriptional and secretory profile that promotes vascular sprouting [3] . BMP8B also involve in activation of caspase-3 and -9, and apoptosis to inhibit pancreatic cancer cell growth [5] .
