长期小鼠脊髓器官型切片培养作为验证脊髓损伤细胞移植的平台

Executive Industry Relevance

Long-term mouse spinal cord organotypic slice culture provides a robust ex vivo platform for validating cell transplantation strategies in spinal cord injury research. This system enables predictive assessment of neural stem cell survival, integration, and maturation prior to costly in vivo studies, supporting early-stage de-risking and portfolio triage. By facilitating preclinical screening of cell therapies, it enhances translational continuity and reduces reliance on animal models.

Strategic Applications in Biopharma R&D
