Q graft EK醫學新知報導

#Q_graft®, 一個即將為大家注意到的stem cell 採集設備，將會廣範的運用在各項治療上

 

「SVF cell harvesting at the point-of-care」

The new compact Q-graft® system for the intraoperative separation and collection of adipose regenerative cells – stromal vascular fraction (SVF) and adipose stem cells (ASC) – 

Q-graft® system是一次性設備，在同一次手術中從抽脂的脂肪進行分離及收集具有「再生特性」的細胞，其中包含了 SVF & ASC (ADSC)

will enhance and facilitate the research and clinical applications of adipose derived regenerative cells in many therapeutic indications.

臨床上以及研究領域都會因為脂肪再生細胞而增加許多治療上的運用

The Q-graft® system consists of

• the single-use Q-graft® collector and

• the device Q-graft® control.

The Q-graft® collector allows to collect and concentrate the lipoaspirate and to separate the regenerative cells (SVF and ASC/adMSC) in one sterile closed system, directly on the sterile instrument table in the operating room or in the research laboratory.

Q-graft® system收集器能在手術房無菌操作的狀態下進行SVF&ASC的收集與濃縮

The corresponding control unit Q-graft® control regulates the functions of the single-use Q-graft® collector. The Q-graft® collector is placed on top of Q-graft® control, directly on the sterile operating or instrument table. Q-graft® control regulates the warming and mixing of the lipoaspirate during incubation, and the cross flow filtration during the concentration of the SVF cell suspension.

Q-graft® system control 則負責調節收集器的功能。加熱，攪拌，以及濃縮SVF液體

The lipid free SFV cell suspension is directly sampled from the sterile Q-graft® collector into a syringe via 

最後，這清純不含脂肪細胞的SVF就這樣收集起來了。

註記：

SVF為Stromal-Vascular Fraction的縮寫，中文稱做「基質血管因子」，SVF包含脂肪前驅細胞、間質幹細胞、纖維母細胞、平滑肌細胞、內皮細胞、血液細胞等，前揭細胞是脂肪、結締纖維組織、血管及其他與中胚層有關組織的前驅物，意即SVF(基質血管因子)將來可以衍生成為新的脂肪細胞和血管。

小編： 目前對於fat graft 用在組織再生國內外有相當多的研究，從fat fell 萃取的SVF or ASC 更是具有分化再生修復的功能。很值得期待fat aspirate 萃取的SVF &ASC 未來臨床上的運用
