Methods and kits for producing cellular fractions enriched in adipose derived stem cells. Methods are provided where adipose tissue obtained from liposuction is enzymatically treated using a solution containing collagenase and divalent cations prior to the application of traditional methods of stromal-vascular fraction isolation. The enzymatic solutions may contain collagenase types I and II to a final concentration of about 0.001 mg/ml to 0.010 mg/ml. The divalent cations may be present as calcium, magnesium, and zinc chloride. The final concentration of calcium, magnesium, and zinc may range from about 0.001 to 0.1 micromolar; about 0.005 to 0.5 micromolar; and about 0.0015 to 0.15 micromolar, respectively. The enzymatic solutions may be generated using a kit where the collagenase and divalent components are held in separate containers until just prior to use. The cellular fractions isolated in this manner may be used in autologous fat grafts in therapeutic applications.
