Adipose stem cells on the basis of tumor transformation
Mesenchymal stem cells thanks to their differentiated multipotent ability are considered the most promising candidate for tissue engineering and regenerative medicine. The source of mesenchymal stem cells up to about 20 years was represented by the bone marrow, but due to their limited amount of cells together with a very invasive and painfull surgical treatment, poorly accepted by patients, has led the scientific community to investigate an alternative mesenchymal stem cells source with similar properties. In particular, the adipose tissue has attracted the greatest interest thanks to its relative abundance, the easy of availability and the large amounts of mesenchymal stem cells which are…
Cancer Stem Cells: From Birth to Death
2019
Abstract Conspicuous investigations have proven the role of cancer stem cells (CSCs) in the onset and progression of a plethora of liquid and solid neoplasms. CSCs are endowed with the capability of initiating tumor growth and becoming dormant at distant organ sites just waiting for optimal conditions amenable for metastatic outgrowth. This cancer subpopulation is inherently resistant to anticancer therapeutics, and its targeting could avoid metastatic disease, which is largely incurable, and clinical relapses. CSCs are considered the Achilles heel of cancer. However, many efforts are necessary to identify univocal CSC markers as well as specific CSC biomarkers of therapeutic response. Here…
Malignancy course of pituitary adenoma in MEN1 syndrome: Clinical-Neuroradiological signs
2020
Pituitary carcinomas (PCa) are extremely rare, indistinguishable from pituitary adenomas on histopathological grounds and have a poor prognosis. Most PCa start as PRL or ACTH secreting tumors in males, with relapsing invasive behaviour, refractoriness to medical and radiotherapy and increasing hormonal levels. The presence of distant metastases is still required for the diagnosis of PCa. The association with genetic endocrine diseases must be taken into account, since it adds further risk of evolution towards malignancy. Intradural spinal metastases have also been reported, so a complete craniospinal MR evaluation is recommended, when clinically indicated. We report a case of PCa, associate…
