ABSTRACT
Understanding peripheral nerve repair requires the evaluation of 3D structures that serve as platforms for 3D cell culture. Multiple platforms for 3D cell culture have been developed, mimicking peripheral nerve growth and function, in order to study tissue repair or diseases. To recreate an appropriate 3D environment for peripheral nerve cells, key factors are to be considered including: selection of cells, polymeric biomaterials to be used, and fabrication techniques to shape and form the 3D scaffolds for cellular culture. This review focuses on polymeric 3D platforms used for the development of 3D peripheral nerve cell cultures.
ABSTRACT
The medullary thyroid carcinoma (MTC) is a rare neoplasia occurring during childhood. At present time the molecular examination of the proto-oncogen RET, related to syndromes of multiple endocrine neoplasia (MEN II) and familial medullary thyroid carcinoma (FMTC) to allows identify patients with risk of suffering of medullary thyroid carcinoma in early ages, before the disease becomes clinically pronunced. Children with familial antecedents of MEN II or FMTC were biochemically (pentagastrin-stimulated) and genetically studied with the purpose of determining the risk of developing a MTC and in order to assess the possibilities of making a prophylactic thyroidectomy.
