简介：
Overview
This protocol provides a simple and efficient way to propagate human pluripotent stem cells (hPSCs) using conditioned media derived from the human placenta in a gelatin-coated dish. This method eliminates the need for additional exogenous supplementation or hPSC-specific synthetic substrata.

What are human pluripotent stem cells?
Human pluripotent stem cells (hPSCs) are cells that can differentiate into any cell type in the body, making them valuable for research and therapy.
Why use conditioned media from human placenta?
Conditioned media from human placenta contains growth factors and nutrients that support the growth of stem cells without the need for synthetic additives.
How does gelatin coating benefit cell culture?
Gelatin coating provides a natural substrate that promotes cell adhesion and growth, mimicking the extracellular matrix found in vivo.
What are the advantages of this method?
This method is cost-effective, simplifies the culture process, and utilizes human-derived materials, enhancing the physiological relevance of the stem cell environment.
How often should hPSCs be subcultured using this method?
hPSCs should be subcultured every four to five days to maintain optimal growth conditions.
Can this method be used for other types of stem cells?
While this method is specifically designed for hPSCs, similar principles may be applied to other stem cell types with appropriate modifications.
