“…Understanding photoreception sparks new therapeutic options for maladies robbing our most prominent sense. And, unexpectedly, photosensitivity in non-ocular cells may have impressive implications for regenerative medicine: As Fan et al 2,3 demonstrate, light can enhance regenerative potential of adipose-derived stromal/stem cells (ASCs) and prolong their regenerative properties, thus adding a new dimension to research aiming at regenerative therapies.…”
