After this period, cells were fixed and used for the determination of alkaline phosphatase (ALP) activity and von Kossa staining for the detection of mineralization.
Some of the histiocytes had basophilic intracellular MG bodies (Figure 1), which were round bodies of varying sizes that reacted positively with the periodic acid-Schiff and von Kossa stains.
The induced cells were stained with von Kossa to confirm osteogenesis, safranin O to confirm chondrogenesis, and oil red O to confirm adipogenesis.
(c) DPCs were cultured in osteogenic induction medium for 14 days, and the mineralized nodule formation was assessed by von Kossa staining (scale bar = 100 [micro]m).
After 4% PFA fixation and positive colonies were counted, mineralized bone nodule formation was assessed by double labeling for mineral (von Kossa stain) and alkaline phosphate (ALP).
von Kossa staining was performed to show the mineralization and calcium deposition of differentiated cells as a marker of osteogenic transformation.
Se pueden observar mejor con el uso de otras tinciones como von Kossa (para calcio), PAS (periodic-acid-Schiff) y azul de Prusia.
Este material tambien se encuentro en la membrana basal de los tubulos proximales y en mayor cantidad en la zona cercana a la medula, resultando positivo a calcio con la coloracion Von Kossa (Figura 4).
The von Kossa method for quantifying calcium crystal formation and deposition was performed as described previously (5).
