cells in recipients.

The frequency of HSPCs in the adipose tissue found in the study was significantly less than that found in bone marrow (approximately 0.2 percent of the HSPCs found in total bone marrow). Therefore, researchers wanted to determine whether the SVF might be used practically as an alternative source of HSPCs. Fortunately, according to the researchers, a vast amount of the SVF in adipose tissue can be easily obtained from patients using conventional liposuction and isolation methods that are safe and relatively pain-free.

"These study results suggest that more HSPCs might be obtained from the stromal vascular fraction through increased mobilization of these cells from the bone marrow using G-CSF," said Dr. Koh. "So once a technology can be defined to purify HSPCs from the stromal vascular fraction, we believe adipose tissue may be a good alternative and novel resource for obtaining functional and transplantable HSPCs."

The research team is actively extending their research in this area, including plans for a human clinical study. They also emphasize the need for a clinically safer and more efficient method for isolating the HSPCs from the adipose tissue.
