Alizarin red staining. Micromass of hTERT-RA 516 FLSs cultured in the absence of ATP. There were no calcium deposits detected (first photo from the left). Micromass of hTERT-OA 13A FLSs cultured in the absence of ATP. Small amounts of calcium deposits were detected within the micromass (second photo from the left). Micromass of hTERT-OA 13A FLSs cultured in the absence of ATP. Large amounts of calcium deposits were detected in the fragments of the micromass, but not within the micromass (third photo from the left). Micromass of hTERT-OA 13A FLSs cultured in the presence of ATP. Large amounts of calcium deposits were detected within the micromass (far right photo).
