An absence of folate when sperm are forming causes alterations in them that affect the mice which grow from the eggs those sperm fertilise.
Furthermore, Shankaran et al, demonstrated for the first time that tumours which grew in immunodeficient mice were more immunogenic than tumours arising in immunocompetent mice, which fortified Burnet and Thomas' original theory of immunosurveillance and led to the formal articulation of the immunoediting hypothesis in 2002 (Dunn et al, 2002).
Except for the ATM+/+/p53−/− and ATM−/−/p53−/− mouse cells, which grow as a monolayer and do not form colonies, all other cell lines used in these experiments form well-defined individual colonies when seeded sparsely on standard tissue culture plates.
Tamoxifen-resistant breast tumours, which grew in nude mice after long-term treatment with tamoxifen, remained sensitive to growth inhibition by fulvestrant (Osborne et al, 1994).
Only clones which grew in nude mice formed colonies in semi-solid medium, and each responded differently to the influence of medium that had been conditioned by the growth of UCRU BL 17CL, suggesting the possible secretion of a growth factor by these cells.
The tumours, which grew on the flanks of the mice, had features of cellular adenocarcinomas, with poor glandular differentiation.
As described in the Coq9 R239X, by postnatal day 21, Coq9 Q95X mice had also lost their body hair (Fig 1A), which grew back during the next hair growth cycle.
Metastatic tumors which grew in the abdominal cut also weighed less in diclofenac treated mice, in all experiments, yet this effect did not achieve statistical significance.
One was A15, which grew rapidly as compact, tight colonies with a dome-shaped appearance) and typical mouse ESC characteristics.
