Human Secretomes, Plant Exosomes, and Hybrid Secretomes Intradermal Injections for Hair Regeneration: Experimental Study.

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
Background: Hair follicle regeneration depends on coordinated interactions between different cells and signaling pathways controlling proliferation. Biologically derived injectable formulations, including human secretomes, plant exosomes, and hybrids, are emerging as potential therapeutics, yet their efficacy in intact skin is not understood. The aim of this research was to evaluate and compare the effects of human adipose-derived secretomes, plant-derived exosomes, and a hybrid exosome formulation on hair regeneration in intact skin. Methods: A randomized, blinded, controlled study was conducted in healthy hamsters. Each animal received two intradermal injections of human secretomes, plant exosomes, hybrid secretomes, or saline with untreated animals as baseline controls. Skin biopsies were collected at baseline, 73 days, and 93 days. Histology (H&E) assessed follicular morphology, and immunohistochemistry for Ki67, β catenin, and CD34 quantified proliferation, Wnt activation, and stem cell involvement. Results: Ki67-positive cells were highest in hybrid secretomes, followed by plant exosomes and human secretomes, with the lowest levels in controls. Nuclear β catenin localization was most pronounced in human secretome-treated follicles, followed by plant exosomes and hybrid secretomes, whereas controls were largely negative. CD34 expression was highest in hybrid secretomes, followed by human secretomes and plant exosomes, with minimal staining in controls. Conclusions: The hybrid secretomes most effectively stimulated proliferative and stem cell-associated markers, whereas human secretomes showed strong Wnt/β catenin activation, highlighting differential mechanistic effects of these formulations.
