Association between Donor Age and Osteogenic Potential of Human Adipose Stem Cells in Bone Tissue Engineering.
Level 5 - mechanism / opinion, no new human data
Narrative review synthesizing existing bench/in vitro literature
PubMed 38392210 · doi:10.3390/cimb46020092
What was done
This review evaluated existing literature concerning the impact of human donor age on the osteogenic differentiation potential of adipose stem cells (ASCs) and analyzed potential reasons for conflicting results in the field.
What was found
The abstract reports no quantitative data or numerical outcomes. It reports an overall poor agreement across studies regarding donor age effects on ASC osteogenic capacity, identifying contributing confounders such as donor characteristics (gender, lifestyle, metabolic status) and experimental variability (cell passaging, cryopreservation, culture conditions, differentiation protocols, and readout methods).
Why it matters
Clarifying how donor age impacts ASC functionality is necessary for assessing the viability of autologous cell therapies for bone tissue engineering in older clinical populations.
Limits
As reported in the abstract, the review is a narrative synthesis without reported systematic search methods or study counts. The underlying primary evidence is restricted to in vitro studies with substantial methodological variation.
