The microscopic structure during directional solidification of human red blood cell suspensions with a hematocrit of 10% was investigated, using three different solutions : physiological saline, physiological saline with 20% v/v glycerol, and physiological saline with 20% v/v glycerol and 20mg/ml antifreeze proteins, and to understand the influence of hematocrit it was compared with the result for the hematocrit of 1% reported previously. The ice crystal structure and the ice-cell interaction were found to be different between the three solutions. This result is basically similar to that for the hematocrit of 1%. While the hematocrit of 1% rarely causes cell-cell interaction in all the solutions, the hematocrit of 10% remarkably causes cell-cell contacts and the resultant cell-cell interaction in physiological saline alone. These results show that the degree of cell-cell interaction depends upon the morphological characteristics of ice crystals, the manners of the ice-cell interaction, and the hematocrit strongly.
