Research and Development
Up until a decade ago, the classic paradigm of wound healing, involving stem cells restricted to organ-specific lineages, had never been seriously challenged. Since then, the notion of adult stem cells having cellular plasticity or the ability to differentiate into non-lineage cells has emerged as an alternative explanation. To be more specific, hematopoietic progenitor cells (that give rise to mature cells in the blood) may have the ability de-differentiate back into hematopoietic stem cells and/or transdifferentiate into non-lineage cells, such as fibroblasts.
