Our results highlight the crucial role of ETP as an obesity-associated factor that promotes tumor growth in the context of adipocyte interactions with tumor and stromal cells. (jci.org)
For example, in addition to promoting sleep, melatonin can also stop tumor growth and protect against the spread of cancer cells. (cdc.gov)
Now pipette the tumor cells up and down several times to re-suspend the cell solution, and load a 25 microliter removable needle syringe, equipped with a 32 gauge needle, with 10 microliters of the cells. (jove.com)
Wipe the outside of the loaded needle with a sterile alcohol pad to remove any external tumor cells, taking care to avoid needle sticks. (jove.com)
A cell line derived from cultured tumor cells. (lookformedical.com)
CONCLUSION: High ß2-GPI expression levels in tumor cells of breast cancer patients were independent factors predicting a better OS and DFS. (bvsalud.org)

A mammary tumor is a neoplasm originating in the mammary gland. (wikipedia.org)

Tumour measurement recorded from the in vivo experiment, shows that the size of tumour decreased in EP54 group whereas the PMX205 group, the tumour maintain its own size. (upm.edu.my)
In vivo treatment of tumors with the Hedgehog inhibitor vismodegib reduced CAF and CSC expansion, resulting in an overall delay of tumor formation. (mdc-berlin.de)

Obesity is influenced by a number of factors, and while veterinarians report that neutered animals do have a tendency to weigh more than intact animals, it can occur regardless of the animal's age when the surgery was performed. (aspcapro.org)
Although mammary tumors can occur at a younger age, they have a higher occurrence after 18 months of age. (ratguide.com)

As the name implies, they are located near the thyroid gland in the neck, although the number and particularly the location are quite variable. (msdmanuals.com)

A good general physical exam is needed to find the location, size, and character of all the mammary masses and assess local lymph node enlargement. (acvs.org)

These slow-growing, benign fatty tumors form soft, lobulated masses enclosed by a thin, fibrous capsule. (medscape.com)
