The tumor microenvironment (TME) includes diverse cellular components such as mesenchymal stem cells (MSC) and immune cells. MSC are a subset of heterogeneous cell populations characterized by the expression of CD105, CD73, and CD90 that can differentiate into chondrocytes, osteoblasts, and adipocytes in vitro. They are known to have immunomodulatory capabilities. Our aim was to isolate and characterize the immunomodulatory capabilities of MSC from pituitary tumors (P...

Pituitary adenomas (PA) are primarily benign lesions with monoclonal origins from the adenohypophyseal cells and represent 10-15% of all intracranial tumors. Tumors derived from POU1F1 cell lineage are GH-, TSH-, and PRL-secreting tumors that cause important syndromes such as acromegaly, hyperthyroidism, and sexual dysfunction, respectively. Surgical resection is the first line of treatment; the secondary treatment is pharmacological; despite having targets pharmacological in ...
