The report behind the claim
Treated and control tissue had differing spectral signatures interpreted as changes in proteins and lipids. Spectral separation is not direct proof of durable vascular function or clinical recovery.

The experiment in view
The study used rat aortic tissue collected after unilateral adrenalectomy. Its principal measures were infrared spectral bands and multivariate separation. Treated and control tissue had differing spectral signatures interpreted as changes in proteins and lipids.
Reading the result closely
A classifier can distinguish samples even when the biological meaning of the distinction remains uncertain. Protein-associated bands are indirect measurements. They should not be rewritten as repaired arteries without independent structural and functional confirmation.
The boundary of the finding
Spectral separation is not direct proof of durable vascular function or clinical recovery.
Related evidence, kept separate
BPC-157 after one adrenal gland was removed in rats examines early vascular, pressure, organ and molecular changes. Here, the measured endpoint was infrared spectral bands and multivariate separation. Those outcomes belong to separate experiments; one is not a replication or a human confirmation of the other.
