Erythrocyte deformability: Erythrocyte deformability refers to the ability of erythrocytes (red blood cells, RBC) to change shape under a given level of applied stress, without hemolysing (rupturing). This is an important property because erythrocytes must change their shape extensively under the influence of mechanical forces in fluid flow or while passing through microcirculation.Erythrocrine: Erythrocrine describes red blood cell or erythrocyte for production and release of signaling molecules. The term “erythrocrine“ was coined by Song et al.Erythrocyte aggregation: Erythrocyte aggregation is the reversible clumping of these cells under low shear forces or at stasis. Erythrocytes aggregate in a special way, forming rouleaux.Hemorheology: Hemorheology, also spelled haemorheology (from the Greek ‘αἷμα, haima "blood" and rheology), or blood rheology, is the study of flow properties of blood and its elements of plasma and cells. Proper tissue perfusion can occur only when blood's rheological properties are within certain levels.Partial cloning: In the field of cell biology, the method of partial cloning (PCL) converts a fully differentiated old somatic cell into a partially reprogrammed young cell that retains all the specialised functions of the differentiated old cell but is simply younger. The method of PCL reverses characteristics associated with old cells.Journal of Rheology: Journal of Rheology is a peer-reviewed scientific journal publishing original (primary) research on all aspects of rheology, the study of those properties of materials which determine their response to mechanical force. It is published bimonthly by the Society of Rheology through the American Institute of Physics.Erythrocyte fragility: Erythrocyte fragility refers to the propensity of erythrocytes (red blood cells, RBC) to hemolyse (rupture) under stress. It can be thought of as the degree or proportion of hemolysis that occurs when a sample of red blood cells are subjected to stress (typically physical stress, and most commonly osmotic and/or mechanical stress).
