Promotion of stem cell proliferation by vegetable peptone.

Area of Science:

• Stem cell biology
• Biotechnology
• Regenerative medicine

Background:

• Animal-derived components in cell culture pose contamination risks.
• Eliminating animal products is crucial for cell culture-derived therapeutics.
• Investigating plant-based alternatives like vegetable peptone is essential.

Purpose of the Study:

• To evaluate the proliferative effect of vegetable peptone on adult stem cells without serum.
• To explore the underlying mechanisms of vegetable peptone-induced stem cell proliferation.
• To assess vegetable peptone as a serum-free alternative in cell culture.

Main Methods:

• Cell viability assessed via MTT assay.
• Cell proliferation measured using Click-iT EdU flow cytometry.
• Cytokine gene expression analyzed using MILLIPLEX human cytokine ELISA kits.

Main Results:

• Vegetable peptone significantly increased viability and proliferation of CB-MSCs and ADSCs.
• Treatment with vegetable peptone led to a significant upregulation of VEGF, TGF-beta1, and IL-6.
• These cytokine changes were observed in both CB-MSC and ADSC cultures.

Conclusions:

• Vegetable peptone effectively promotes the proliferation of CB-MSCs and ADSCs.
• The proliferative effect of vegetable peptone is associated with the induction of VEGF, TGF-beta1, and IL-6.
• Vegetable peptone shows promise as a serum-free supplement for stem cell culture.
