Spheroid and sphere

WebMar 28, 1990 · The problem of map projection is stated, and the basic terminology is introduced. The required fundamental mathematics is reviewed, and transformation theory is developed. Theories from differential geometry are particularized for the transformation from a sphere or spheroid as the model of the earth onto a selected plotting surface. WebCellular aggregation of RA-hMSCs was observed and cells were aggregate into a single sphere. Following treatment of RA patient’s synovial fluids into the RA-hMSCs, spheroids formed RA-hMSCs showed significantly (p < 0.05) higher expression of TNFα stimulated gene/protein 6 (TSG-6) than the monolayer cultured RAhMSCs.
