    • Methods of isolating cells from adipose tissue that have potential to differentiate into cells of mesenchymal origin, including cells of chondrogenic, osteogenic, adipogenic, and/or myogenic origin, comprising: (a) subjecting adipose tissue to an electromagnetic, sonic, or other wave energy source; and (b) centrifuging the tissue to form a pellet comprising stem cells. In various embodiments, the method is carried out without any enzymatic digestion of the adipose tissue. In other embodiments, the method additionally comprises enzymatically digesting the tissue. In various embodiments, methods comprise subjecting the tissue to ultrasonic energy. In some embodiments, the method does not comprise enzymatic digestion of the adipose tissue. In other embodiments, the method additionally comprises enzymatically digesting the tissue. Methods are also provided for intraoperative harvest and delivery of autologous stem cells to the site of acute or chronic wounds. In one embodiment, an autologous supply of stem cells is provided for operative use.
    • 从具有潜在分化成间充质来源的细胞的脂肪组织分离细胞的方法,包括软骨形成,成骨,脂肪形成和/或肌原性来源的细胞,包括:(a)使脂肪组织进行电磁,声波或其它波 能量源; 和(b)离心组织以形成包含干细胞的丸粒。 在各种实施方案中,该方法不进行任何酶消化的脂肪组织。 在其它实施方案中,该方法还包括酶促消化组织。 在各种实施例中,方法包括使组织经受超声能量。 在一些实施方案中,该方法不包括脂肪组织的酶消化。 在其它实施方案中,该方法还包括酶促消化组织。 还提供了用于术中收获和将自体干细胞递送至急性或慢性伤口部位的方法。 在一个实施例中,提供干细胞的自体供应用于操作使用。
