In an intratracheal instillation study of mice, three types of SWCNTs were investigated (Lam et al. 2004)—two types made by the HiPCO method and one by the electric arc method.
The mice had two types of mitochondria that differed by one letter of the genetic code.
Normal wild-type mice developed two types of central sleep apneas (CSA), that is, post-sigh and spontaneous apneas, as normal humans do.
They treated blood cells from six mice with two types of messenger proteins that can transform T cells into regulatory T cells and exposed them to cells from the donor animals.
Wild type mice express two types of cone pigment: an S pigment, with maximal absorption at 360 nm, and an M pigment, with maximal absorption at 510 nm [43].
Before implantation of the tumor cells, the healthy mice manifested two types of autoantibody reactivity patterns detectable at 1∶5 serum dilution: a collective pattern common to the group (marked by a relatively low degree of individual variation) and individual patterns for each mouse (marked by a high degree of variation between mice).
Hoffman's team had found in earlier experiments that interleukin-12, when injected into a mouse, causes two types of immune cells--T-cells and natural killer cells--to produce higher than normal levels of another chemical, interferon-gamma.
In mice, three main types of hair follicle guard hairs, awl hairs, and zigzag hairs are associated with combinations of three types of nerve endings.
To explore this point, we prepared two conditional KO mice in which TrkB was deleted from Müller glia (TrkB GFAP KO mice) or from two types of retinal neurons (RGCs and amacrine cells).
The seizures we observed in SYN mice were of two types.
