[摘要]
細胞治療給許多疾病帶來希望,已經(jīng)成為業(yè)界關注的熱點之一。盡管細胞治療在治療效力方面取得了快速發(fā)展,但移植細胞在體內(nèi)的生物分布及機制尚不清楚。細胞體內(nèi)示蹤技術的不足嚴重影響了細胞治療的臨床轉(zhuǎn)化應用。目前,多種細胞體內(nèi)示蹤技術已經(jīng)應用于臨床前研究,如染料標記追蹤、放射性同位素追蹤、納米顆粒標記技術、報告基因技術、實時定量聚合酶鏈式反應(qRT-PCR)技術、組織學技術等,但缺乏完美可靠的示蹤技術。為比較不同的示蹤技術,對目前研究中應用的細胞示蹤技術進行綜述。

[Abstract]
Cellular therapy has brought hope to many diseases and has become one of the hot spots in the pharmaceutical world. Although cellular therapy has made rapid progress in therapeutic efficacy, the biodistribution of cellular therapy products in vivo and the mechanisms involved are still unclear. Inadequate in vivo cellular tracing techniques have hindered the mastery of cell fate and severely impacted the clinical translation of cellular therapy applications. A variety of in vivo cell tracing techniques have been applied in preclinical studies, such as dye labeling tracing, radioisotope tracing, nanoparticle labelling techniques, reporter gene techniques, quantitative real-time polymerase chain reaction (qRT-PCR) techniques, and histological techniques, but a perfect and reliable tracing technique is lacking. In order to compare the different tracing techniques, a review of the cellular tracing techniques applied in current research is presented.
