The human umbilical cord-mesenchymal stem cell secretome regulates hair growth and cycle transition by promoting methylthioadenosine synthesis via the PI3K/AKT/mTOR pathway.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe human umbilical cord (hUC)-mesenchymal stem cell (MSC) secretome (SCT) is a cell-free therapy that may emerge as a novel therapeutic strategy for hair loss prevention. Here, we aimed to elucidate the underlying mechanisms through which SCT regulates hair growth and cycle transition.
methodsUsing C57BL/6 mice, ex vivo follicles, and cell experiments, we studied the effects and mechanisms of SCT on hair growth and cycling using untargeted metabolomics and phosphoproteomics. A three-month double-blind clinical study was conducted to validate the effects of SCT on human hair.
resultsSCT promotes the telogen-to-anagen transition, hair thickening, and elongation of the vibrissae in mice; regulates dermal papilla cells and hair matrix cells through cysteine and methionine metabolism; and stimulates methylthioadenosine synthesis in hair matrix cells by activating the PI3K/AKT/mTOR signaling pathway. Clinical studies demonstrated that SCT increased human hair density and average hair diameter. Scalp physiological tests and subjective feedback indicated no related adverse reactions on the scalp or hair.
conclusionsSCT promoted hair growth, thickening, and the hair follicle cycle via the PI3K/AKT/mTOR signaling pathway. This research provides a basis for the application of cell-free alternatives in hair care and hair loss prevention.
