Texas A&M University Study
A groundbreaking study led by Texas A&M University has uncovered a dormant regenerative ability in mammals. By applying a two-step process involving growth factors FGF2 and BMP2, researchers successfully reconstructed bone, joint, ligament, and tendon tissue following amputation. The findings were published in Nature Communications on June 18.
Research Approach
Under the direction of Professor Ken Muneoka, the team developed a technique with two distinct phases:
- Step one involves administering the growth factor FGF2;
- Step two follows with BMP2.
This strategy aims to redirect fibroblasts—cells that typically produce scar tissue after an injury. As Professor Muneoka explained:
“It’s as if the cells can go in two directions—either form a scar or form a blastema. We focused on steering the fibroblasts already present at the wound site.”
The method opens up new avenues for tissue regeneration, especially in situations where scarring usually occurs. “First, you shift the cells away from scarring, then you give them instructions on what to build,” Muneoka said. Notably, the technique does not require introducing stem cells, since fibroblasts are already located at the injury site. “You don’t need to harvest stem cells and inject them back. They’re already there—you just have to learn how to make them behave the way you want,” he added.
Larry Suva further noted that
“the cells we thought were unprogrammable actually are programmable. The potential isn’t missing—it’s just hidden.”This discovery could transform how injuries and amputations are treated in mammals, offering fresh possibilities for medical care.

The revelation of fibroblasts’ regenerative capacity may significantly impact medical practice, particularly in trauma and amputation treatment. This research underscores the importance of understanding cellular regeneration mechanisms, which could lead to new therapies that reduce the need for complex surgeries. Further studies in this field may unlock new treatment possibilities not only for mammals but also for humans.
