Embryoid bodyEmbryoid bodies (EBs) are three-dimensional aggregates of pluripotent stem cells. EBs are differentiation of human embryonic stem cells into embryoid bodies comprising the three embryonic germ layers. The pluripotent cell types that comprise embryoid bodies include embryonic stem cells (ESCs) derived from the blastocyst stage of embryos from mouse (mESC), primate, and human (hESC) sources. Additionally, EBs can be formed from embryonic stem cells derived through alternative techniques, including somatic cell nuclear transfer or the reprogramming of somatic cells to yield induced pluripotent stem cells (iPS).
Trichrome stainingTrichrome staining is a histological staining method that uses two or more acid dyes in conjunction with a polyacid. Staining differentiates tissues by tinting them in contrasting colours. It increases the contrast of microscopic features in cells and tissues, which makes them easier to see when viewed through a microscope. The word trichrome means "three colours". The first staining protocol that was described as "trichrome" was Mallory's trichrome stain, which differentially stained erythrocytes to a red colour, muscle tissue to a red colour, and collagen to a blue colour.
Animal–industrial complexAnimal–industrial complex (AIC) is a concept used by activists and scholars to describe what they contend is the systematic and institutionalized exploitation of animals. It includes every economic activity involving animals, such as the food industry (e.g., meat, dairy, poultry, apiculture), animal testing (e.g., academic, industrial, animals in space), medicine (e.g., bile and other animal products), clothing (e.g., leather, silk, wool, fur), labor and transport (e.g.
