Multiscale Stem Cell Technologies for Osteonecrosis of the Femoral Head

Abstract EN

The last couple of decades have seen brilliant progress in stem cell therapies, including native, genetically modified, and engineered stem cells, for osteonecrosis of the femoral head (ONFH).

In vitro studies evaluate the effect of endogenous or exogenous factor or gene regulation on osteogenic phenotype maintenance and/or differentiation towards osteogenic lineage.

The preclinical and clinical outcomes accelerate the clinical translation.

Bone marrow mesenchymal stem cells and adipose-derived stem cells have demonstrated better effects in the treatment of femoral head necrosis.

Various materials have been used widely in the ONFH treatment in both preclinical and clinical trials.

In a word, in vivo and multiscale efforts are expected to overcome obstacles in the approaches for treating ONFH and provide clinical relevance and commercial strategies in the future.

Therefore, we will discuss the above aspects in this paper and present our opinions.
