Targeted partial reprogramming of age-associated cell states: skin-relevant OSK parameters

Targeted partial reprogramming of age-associated cell states: skin-relevant OSK parameters

''Source'': Science Translational Medicine (2024), ''Targeted partial reprogramming of age-associated cell states improves markers of health in mouse models of aging'' (OSK delivered via AAV to Cdkn2a+ cells).

Skin-relevant parameters extractable from the report

# ''Organism'': naturally aged wild-type mice
# ''Tissue'': skin; the report snippet specifically notes ''intradermal injection'' for the wound-healing experiment
# ''Intervention'': AAV carrying Cdkn2a-OSK; targeted/inducible partial reprogramming rather than global systemic OSK
# ''Functional outcome'': improved wound healing in aged mice
# ''Safety/identity note'': the snippet reports improved aging phenotypes / lifespan without obvious tumor increase, and in human fibroblasts reduced inflammation-related genes without altering cell-cycle genes

Comparison use

This study is a ''skin-local partial reprogramming'' positive, but it is ''not'' a direct comparator to Topical ABT-263 in aged mouse skin: original study and readouts because the OSK route is intradermal AAV-based while ABT-263 is topical small-molecule exposure. Any head-to-head claim therefore needs route-matched or exposure-matched design, not just shared tissue and wound readout.
