Pluripotin (SC1) is widely used in stem cell research for its ability to maintain the pluripotency of embryonic stem cells (ESCs) without the need for feeder cells or leukemia inhibitory factor (LIF). It works by inhibiting differentiation pathways, allowing ESCs to remain undifferentiated and self-renewing. This makes it a valuable tool in regenerative medicine, enabling large-scale cultivation of stem cells for therapeutic applications. Additionally, it is utilized in drug discovery and toxicity testing, as it helps maintain stable stem cell lines for consistent experimental results. Its role in promoting cell proliferation also aids in studying cellular mechanisms and developing treatments for degenerative diseases.
