A short history of regenerative medicine
From skin grafts and bone marrow transplants to engineered tissue — how the field assembled itself.
The field is older than its name. Skin grafting is centuries old; bone marrow transplantation, established in the mid-twentieth century, was arguably the first routine cell therapy — a demonstration that transplanted stem cells could rebuild an entire tissue system.
The modern synthesis dates to the late 1980s and 1990s, when tissue engineering was named and the cells-scaffold-signals framework of The principles of tissue engineering took shape. Cultured skin substitutes reached patients; recombinant BMP-2 and BMP-7 moved growth factors into orthopedic practice. The 2006 description of induced pluripotent stem cells then removed a major ethical and practical constraint on cell sourcing.
The last two decades have been less about single breakthroughs than about confronting limits: vascularization, manufacturing consistency, and the gap described in Translation in regenerative medicine. The trajectory is real, but slower than early enthusiasm suggested.
