Vitronectin (367-378)
Based on 1 Customer Validation
Vitronectin (367-378) corresponds to the 367-378 residue fragment of Vitronectin and is a heparin/glycosaminoglycan-binding peptide. Vitronectin (367-378) acts on cell surface glycosaminoglycans and does not directly bind integrins. Vitronectin (367-378) supports pluripotent stem cell adhesion, proliferation, long-term self-renewal, pluripotency markers, normal karyotype, and undifferentiated culture. Vitronectin (367-378) facilitates the differentiation of human pluripotent stem cells into definitive endoderm and mesoderm. Vitronectin (367-378) can be used in research related to stem cell fate regulation.

Beschreibung
In Vitro
Vitronectin (367-378) (500 ng/mL Noggin; 10 μM SB431542; 5 d) supported an adhesion rate of H9-derived ectoderm not exceeding 50%[1].
Vitronectin (367-378) alone cannot effectively support motor neuron differentiation of H9 cells, leading to cell aggregation and detachment, whereas the Vitronectin (367-378)/cRGD surface supports Map2+ and Map2+/Isl1+ motor neuron differentiation by day 15[1].
Vitronectin (367-378) promotes the differentiation of human pluripotent stem cells into definitive endoderm and mesoderm[1].
Vitronectin (367-378), compared with substrates such as Matrigel that can activate integrins, resulted in lower Akt phosphorylation levels, and the Smad/Akt signaling balance shifted toward mesendodermal differentiation[1].
Vitronectin (367-378) can be displayed on glass and streptavidin scaffolds, supporting human pluripotent stem cell adhesion and expansion[2].
Vitronectin (367-378) (GKKQRFRHRNRKG) supports the attachment and long-term self-renewal of multiple human embryonic stem cell and induced pluripotent stem cell lines; cells cultured on surfaces modified with this peptide maintain a normal karyotype, high expression of pluripotency markers (Oct-4, SSEA-4), and full trilineage differentiation potential[1].
Vitronectin (367-378) (peptide-functionalized surface; mTeSR medium; 6 days) mediates cell attachment by binding to cell surface glycosaminoglycans; treatment with soluble heparin or chondroitinase ABC weakens the adhesion of human embryonic stem cells[2].
Vitronectin (367-378) (combined with cyclic RGD peptide; streptavidin-modified surface; mTeSR medium; 1-2 months) supports human pluripotent stem cell attachment and long-term expansion; after colony formation, the ROCK inhibitor Y-27632 (HY-10071) can be withdrawn from the medium[2].
