(a, c) Preoperative view of patient 1 (with facial contour deformity involving bilateral cheeks) and patient 2 (with facial contour deformity involving right mandibular area), respectively. (b, d) Fat absorption six months after the 1^st session of conventional lipofilling. (e, g) Preoperative view and (f, h) postoperative view of patients in the stem cell group. (e) exhibits preoperative view of a patient with contour deformity of the right mandibular area, and (f) shows postoperative view six months after a single session of ex vivo expanded ASC-enriched lipofilling. (g) represents preoperative view of a patient with contour deformity of the face near the eye, and (f) shows postoperative view six months after a single session of ex vivo expanded ASC-enriched lipofilling in some patients.
