Adipose-derived mesenchymal stem cells represent a relatively novel cell therapeutic modality for promoting bone healing, however they remain relatively uncharacterized on a subpopulation level. Using the forefather algorithm of ScaiVision, CellCNN, the authors were able to exploit CyTOF data to identify an ALP and CD73-double positive population as having a high bone differentiation potential. They could also show that these cells could not only be used to identify promising cell lines for use in bone regeneration, but their levels could also be used as a quality control during manufacturing.

Although it has driven a paradigm shift in how cancer is treated, targeted immunotherapy is oftentimes plagued by low response rates, highlighting the urgent need for biomarkers predictive of response. Here, CellCNN was used to further characterize and confirm the identity of a specific subpopulation of monocytes as being strongly associated with response to anti-PD-1 immunotherapy in stage IV melanoma, paving the road for the selection of tailored treatments for patients.
