Experimental Production of Testicular Teratomas in Mice.
6Madsen (private communication) found that Mg ions lower the Km for 5'-AMP without affecting the Van. Owing to this effect, the inhibition by ATP is markedly diminished in the presence of this metal ion. Similarly, the effect of 5'-AMP on the interaction of phosphorylase with its substrates could be modified by the presence of Mg ions and result in different numerical values for kinetic paramet...
متن کاملFrom testis to teratomas: a brief history of male germ cells in mammals.
In antiquity, many theories were advanced on reproduction and the functions of the gonads. The male genitalia were called "testes" probably from the Latin word "testis" that originally meant "witnesses", because they provide evidence of virility. Through the first dissection of the seminipherous tubules by Renier de Graaf (1668), the discovery of spermatozoa by Antonj van Leeuwenhoek (1677) and...
متن کاملDevelopment of epithelia in experimental teratomas derived from rodent embryos.
Investigation of developmental potential of various embryonal tissues is important for design of new approaches to regenerative medicine aimed at supplementing tissues damaged by trauma or disease. Rodent embryos have been extensively used in experiments designed for investigation of developmental potential to give rise to various types of epithelia such as superficial epithelia, neuroepitheliu...
متن کاملExperimental induction of testicular teratomas in dissociated-reaggregated chimaeric gonads.
Testicular teratomas can be experimentally induced in some strains of mice by grafting 12.5-day male genital ridges to the testes of adults. The grafts develop into testes and most of them have teratomas. The cells of 12.5-day foetal gonads were dissociated and the germ cells and somatic cells were separated. When germ cells were reaggregated with somatic cells and implanted in adult testes, th...
متن کاملTeratomas.
Teratomas are embryonal tumors that normally arise from germ cells [3] and are typically benign. They are defined as being composed either of tissues that are foreign to the area in which they form, or of tissues that derive from all three of the germ layers [4]. Malignant teratomas are known as teratocarcinomas; these cancerous growths have played a pivotal role in the discovery of stem cells ...
