To compare the endothelial cell density (ECD) of corneas stored in organ culture (OC) using CorneaMax/CorneaJet and Tissue-C/Carry-C media.
Three complementary experiments included paired corneas stored in CorneaMax or Tissue-C and subsequently deswelled in CorneaJet or Carry-C. In experiment 1, storage media renewal was performed only for CorneaMax as per the manufacturer's guidelines, with storage/deswelling times of 30/4 days (D). In experiment 2, both storage media were renewed on D4, with storage/deswelling time of 28/2 days. In experiment 3, both storage media were renewed, with storage/deswelling times of 22/4 days. In addition to ECD (in the three experiments), the viable ECD (Hoechst 33342/Calcein-AM staining) and central corneal thickness (CCT) were measured in exp. 2.
In experiment 1 (16 pairs), ECD was significantly higher in CorneaMax than in Tissue-C on D30 (2265 ± 379 vs. 2097 ± 344 cells/mm 2 , P = 0.0248) and postdeswelling (2106 ± 405 vs. 1910 ± 355 cells/mm 2 , P = 0.0290). In experiment 2 (10 pairs), ECD did not differ after 28 days of OC; however, CCT was lower on D4, higher on D28 in Tissue-C, and showed no difference after deswelling. Postdeswelling, viable ECD was significantly higher in CorneaJet versus Carry-C (1647 ± 324 vs. 1436 ± 235 cells/mm 2 , P = 0.0189). In experiment 3 (eight pairs), ECD showed no significant difference.
Endothelial survival is reduced in Tissue-C/Carry-C unless storage is limited to 3 weeks and the medium is renewed. The major corneal edema in Tissue-C may contribute to the reduced ECD.
比较使用CorneaMax/CorneaJet和Tissue-C/Carry-C培养基在器官培养(OC)中储存的角膜的内皮细胞密度(ECD)。
三项补充实验包括将配对的角膜分别储存在CorneaMax或Tissue-C中,随后在CorneaJet或Carry-C中复水。在实验1中,按照制造商的指南仅对CorneaMax进行储存培养基更换,储存/复水时间为30/4天(D)。在实验2中,两种储存培养基均在第4天更换,储存/复水时间为28/2天。在实验3中,两种储存培养基均进行更换,储存/复水时间为22/4天。除了ECD(在三项实验中),在实验2中还测量了活ECD(Hoechst 33342/钙黄绿素-AM染色)和中央角膜厚度(CCT)。
在实验1(16对)中,在第30天(2265±379对2097±344个细胞/mm²,P = 0.0248)和复水后(2106±405对1910±355个细胞/mm²,P = 0.0290),CorneaMax中的ECD显著高于Tissue-C。在实验2(10对)中,OC 28天后ECD无差异;然而,在第4天CCT较低,在第28天Tissue-C中较高,复水后无差异。复水后,CorneaJet中的活ECD显著高于Carry-C(1647±324对1436±235个细胞/mm²,P = 0.0189)。在实验3(8对)中,ECD无显著差异。
除非储存时间限制在3周以内并更换培养基,否则Tissue-C/Carry-C中的内皮细胞存活率会降低。Tissue-C中主要的角膜水肿可能导致ECD降低。
