    Notes: The total numbers of masl cells (MC) in popliteal lymph nodes of homozygous nude (nu/nu) and phenolypicaily normal, heterozygous (+/nu) BALB/c mice are greater than in normal (+/+) BALB/c mice at approximately 6 months of age. The values obtained from 4- to 7-month-old (nu/nu) and (+/nu) mice are twice as high as those from 2- to 3-month-old mice. It is concluded that the thymus does not directly determine the number of MC in lymph nodes, but the presence-of the nu gene or another gene closely linked to the nu gene regulates the number of MC.‘Nude’ mice infected with hepatitis virus accumulate many more MC than do healthy mice.

    Notes: [Auszug] Inbred 5-week-old NMRI mice of both sexes were inoculated into left shanks with 0.2 ml of standard M-MSV diluted 1:5 in phosphate-buffered saline. The virus was prepared according to Chanaille et al.13 (IO3 TID50 in 0.2ml). Mice were killed at various intervals between the 3rd and 190th days after ...

    Notes: Summary The absolute number of mast cells in regional lymph nodes decreases on the 5th day after stimulation by allogeneic lymphocytes and semisyngeneic leukaemic cells, despite the enlargement of stimulated lymph nodes. It is postulated that the reaction of lymphatic mast cells could be a sensitive test for tissue incompatibility, and probably also for the presence of tumor associated antigens.

    Notes: Résumé Des épithéliums de muqueuse vésicale de chien, de cobay et de hamster ont été greffés sur des souris préalablement traitées à l'acétate de cortisone. L'induction par ces greffes d'un cartilage et d'un tissu osseux prouve que l'inducteur d'ossification formé et libéré par ces épithéliums manque de spécificité générique. On a montré que le faible pourcentage de l'induction d'ossification est imputable à la faible capacité inductive de cet épithélium et non au manque de sensibilité du tissu conjonctif induit de la souris dans le système allogénique.

    Notes: Summary The relative number of mast cells in the ear lobes' skin (pinna) of nude (athymic) nu/nu and normal (thymic) nu/+ heterozygotes of Balb/c mice was similar. The results obtained contradict some suggestions about the general influence of the thymus on the number of mast cells in the skin and suggest the existence of some local factor(s) in regulation of skin mast cell numbers.

    Notes: Abstract Cell lines capable of inducing cartilage/bone (e.g. HeLa, WISH, CLV-J3, CLV-X, CLV-4 and CLV-14) agglutinate in the presence of Concanavalin A because their membranes contain the appropriate receptors. This indicates that these cell lines may possess surface terminal branched carbohydrates with terminal non-reducing α-D-glucopyranosyl, α-D-mannopyranosyl or β-D-fructofuranosyl residues. Cells devoid of osteogenic properties (T-24, L-929, primary cultures of human and mouse fibroblasts) did not agglutinate in the presence of Concanavalin A, probably because either the receptors were masked or absent. Phytohemagglutinin differed from Concanavalin A in so much as it agglutinated both osteogenic and non-osteogenic cell lines.

    Notes: Summary Small pieces (ca. 2–3×3–5 mm) of the urinary-tract mucosa from noninvasive papillary transitional-cell carcinomas of the bladder (ca. urotheliale papillare, n=33), invasive transitional-cell carcinomas of the bladder (ca. urotheliale papillare infiltrans, n=6, papillary transitional-cell carcinomas of the bladder with squamous metaplasia (ca. urotheliale papillare cum metaplasia planoepitheliale, n=4), transitional-cell carcinomas in situ (ca. urotheliale in situ, n=2), and squamous-cell carcinomas of the bladder (ca. planoepitheliale, n=2) were grafted intramuscularly into cortisone-immunosuppressed mice to test the ability of transformed transitional epithelium to induce heterotopic osteogenesis. Altogether, 156 implants from 47 cases of urinary bladder carcinoma were performed. Histological examination of implants, excised 10–17 days later, revealed relatively good survival of the grafted epithelium, which had proliferated and, in some cases, formed cysts and islands but failed to induce heterotopic osteogenesis in the surrounding host tissues. In nine implants prepared from four cases (noninvasive papillary transitional-cell carcinoma of the bladder and invasive papillary transitional-cell carcinoma of the bladder, two cases each) a small amount of cartilage and/or bone was found in the stroma of grafted tissue. The rarity of this phenomenon — together with the observation that implants of normal human urinary-tract mucosa have never induced the formation of cartilage/bone, whereas in a similar system, dog or guineapig grafts are osteogenic — suggests that the cartilage/bone present in the stroma of implanted cancers is the result of metaplasia of the stroma of the neoplasm and not the product of any osteoinductive potency of human urothelium.

    Description / Table of Contents: Résumé Des cellules épithéliales humaines, obtenues par culture de tissu (de lignée “K”), sont njectées dans les muscles de la cuisse et de la paroi abdominale ou dans le tissu sous-cutané de rats conditionnés par la cortisone. Du cartilage et/ou de l'os se forment dans le tissu musculaire, mais non dans le tissu sous-cutané.
    Abstract: Zusammenfassung Zellen aus der Kultur von menschlichem Epithelialgewebe („K”-Stamm) wurden Cortisonvorbehandelten Ratten in die Bein- oder Bauchwandmuskulatur oder subcutan injiziert. Die Bildung von Knorpel und/oder Knochen wurde in diesen zwei Muskelgeweben leicht ausgelöst; dies war jedoch an den subcutan behandelten Stellen nicht der Fall.
    Notes: Abstract Human epithelial tissue culture line cells (“K” line) were injected into the leg or abdominal wall muscle, or subcutaneously, in cortisone-conditioned rats. Cartilage and/or bone was induced readily in either of the muscular sites, but not subcutaneously.
