An image analyzer Leica Q win V.3 program (Wetzlar, Germany) in the Histology department, faculty of Medicine Ain Shams University was used to measure: Mean total thickness of: Corneal epithelial layer. Descemet��s membrane layer. The number of: Alkaline phosphatase positive cells/high power field CD 44 positive cells/high power field. Vimentin positive cells/high power field Statistical analysis was done using one way ANOVA test performed by SPSS 17 program. The significance of the data was determined by p-value p>0.05 non-significant (NS), p[http://www.selleckchem.com/products/rgfp966.html RGFP966 datasheet] supplemented with 1% penicillin-streptomycin (GIBCO/BRL). Cells were incubated at 37��C�� in 5% humidified Co2 for 12~14 days as primary culture or upon formation of large colonies. When large colonies developed (80~90% confluence), cultures were washed twice with phosphate buffer saline (PBS) and cells were trypsinized with 0.25% trypsin in 1 mM EDTA (GIBCO/BRL) for 5 minutes at 37��C. After centrifugation (at 2,400 rpm for 20 minutes), cells were resuspended with serum-supplemented medium and incubated in (50 cm2 culture flask Falcon). [http://en.wikipedia.org/wiki/PDK4 PDK4] The resulting cultures were referred to as first-passage cultures (6). Morphological identification of BM-derived MSCs: MSCs in culture were characterized by their adhesiveness and fusiform shape (7). characterization using CD29+ and CD45?, CD34?, CD44+ was also performed. Examination [http://www.selleckchem.com/products/pifithrin-alpha.html selleck] of dishes and taking photographs were done using fluorescence inverted microscope (Axiovert 100-ZEISS, Denmark). Determining cell viability by trypan blue stain and the total cell count using hemocytometer. Application of mesenchymal stem cells: MSCs 1��107 cells/ml were injected once in an ear vein 24 hours after induction of corneal alkali burn (8). Results Morphological identification of the primary culture of rabbit BM-MSCs as evident by the inverted microscope On day five of BM culture, colonies of adherent BM-MSCs appeared in the form of star-shaped cells with long processes, central vesicular nuclei and granular cytoplasm. Characterization using CD44+ was evident (Fig. 1A). Characterization using CD29+ and CD45?, CD34? was also detected as well (data not shown). Fig. 1 (A) BM-MSCs, on day five of isolation and culture, showing the appearance of a colony of star-shaped cells with long processes (��), central vesicular nucleus and granular cytoplasm. Notice, a cell appears in the anaphase stage of division (*). ... Histological results Group I: (Control group): H&E stained sections of control group (Group I) showed the four layers of the cornea.
