WebAug 22, 2024 · Each sphere has a coordination number 8 and there are 2 atoms per unit cell. The cubic closest packed, also called face-centered cubic (fcc) has has a sphere at each corner and each face of a cube. Each sphere has a coordination number of 12 and there are 4 atoms per unit cell. WebIdeally, the median sphere diameter of a specific cell line is allready known from previous experiments. For example, MCF-7 cells exhibit a mean diameter of > 150 µM after 10-12 days. Aggregates with < 80 µM should never be counted as positive. Some slowly growing cell lines require more than 7-12 day growth to achieve large enough spheroids ...
