3rd Invitrx warning highlights FDA oversight weakness

The FDA seems oddly slow in oversight of unproven stem cell clinic-related firms like one here in California called Invitrx Therapeutics. I’ve written before about Invitrx, but interactions between them and the FDA have continued including a new warning letter.

Map of R3 stem cell clinic locations
