Effects of lipoxygenase metabolites of arachidonic acid on the growth of human mononuclear marrow cells and marrow stromal cell cultures

open access: yesMediators of Inflammation, 1998
The effects of various lipoxygenase metabolites of arachidonic acid (AA) were investigated on the growth of freshly isolated human bone marrow mononuclear cells and marrow stromal cell cultures. LTB4, LXA4, LXB4, 12-HETE and 15-HETE (1 μM) decreased [3H]-

T cell growth factor: parameters of production and a quantitative microassay for activity.

open access: yesJournal of Immunology, 1978
Several soluble factors have recently been associated with the proliferation and differentiation of thymus-derived lymphocytes. One of these factors present in medium conditioned by T cell mitogen-stimulated lymphocytes has the ability to promote the ...

Human Keratinocytes Catabolize Thymidine

open access: yesJournal of Investigative Dermatology, 1988
Human neonatal foreskin keratinocytes incorporate exogenous thymidine into DNA and proliferate in vitro even after reaching confluence. Keratinocytes also catabolize thymidine, as reported for the first time below. Stratified cultures of keratinocytes reduced the amount of thymidine in the medium by more than 90% within 2 to 4 h. Consequently, the rate

Thymidine catabolism promotes NADPH oxidase-derived reactive oxygen species (ROS) signalling in KB and yumoto cells

open access: yesScientific Reports, 2018
Thymidine phosphorylase (TP) is a rate-limiting enzyme in the thymidine catabolic pathway. TP is identical to platelet-derived endothelial cell growth factor and contributes to tumour angiogenesis.

Interactions of asbestos-activated macrophages with an experimental fibrosarcoma [PDF]

open access: yes, 1983
Supernatants from in vivo asbestos-activated macrophages failed to show any cytostatic activity against a syngeneic fibrosarcoma cell line in vitro. UICC chrysotile-induced peritoneal exudate cells also failed to demonstrate any growth inhibitory effect ...

Labeling DNA with Stable Isotopes: Economical and Practical Considerations

open access: yesBioTechniques, 2001
Labeling DNA with stable isotopes to measure cell proliferation can be a technique as effective as 3H-thymidine labeling without the limitations imposed by using radioisotopes.

Transplantation stimulates interstitial cell migration in hydra [PDF]

open access: yes, 1990
Migration of interstitial cells and nerve cell precursors was analyzed in Hydra magnipapillata and Hydra vulgaris (formerly Hydra attenuata). Axial grafts were made between [3H]thymidine-labeled donor and unlabeled host tissue. Migration of labeled cells
