Despite the significant advances in using animal models in medical research, some preclinical studies from those models failed to be translated into clinical practice successfully. This could be due to subtle differences in the brain…
A spheroid is a three-dimensional (3D) cell culture model that mimics the in vivo environment more closely than traditional two-dimensional (2D) monolayer cultures. Physiologically, spheroids exhibit several distinct characteristics compared to 2D cell cultures. This…
As spheroids grow, oxygen diffusion from the external layers of cells into the core gets limited and this leads to cellular stress, energy deprivation, and eventually necrosis. The development of necrosis in spheroids depends on…
Spheroid cell cultures are defined as 3-dimentional cell aggregates that are formed via spontaneous self-assembly of cells in a cell repellant, non-adhesive surface. It is by far one of the popular anchorage free 3D cell…
Spheroid cell culture is a type of scaffold-free 3D cell culture method. Spheroids are formed by the self-assembly of cells. Generally, spheroid formation takes place in 3 steps (1-3). 1. Formation of loosely packed cell…
