Publication number: 20220288245Abstract: The present invention relates to a radiopharmaceutical compound or composition for Positron Emission Tomography (PET) imaging of interleukin-2 (IL2) receptor positive cells, in particular, 68Ga-radiolabelled interleukin-2 such as a desalanyl-1, serine-125 human interleukin-2 (dsIL2) radiolabelled with a short-lived PET radioisotope (or radionuclide) gallium-68 (68Ga) by using tris-(hydroxypyridinone-maleimide) (THP-mal) as a chelator. The invention concerns also a kit comprising dsIL2 linked to THP-mal which can be added with 68Ga in order to obtain the above mentioned radiopharmaceutical, at room temperature, suitable for PET imaging, a process for the preparation of the radiopharmaceutical and its use in medical and diagnostic field.Type: ApplicationFiled: July 2, 2020Publication date: September 15, 2022Applicant: SAPIENZA UNIVERSITA' DI ROMAInventors: Alberto SIGNORE, Filippo GALLI

Publication number: 20220232820Abstract: Human biliary tree stem/progenitors (hBTSCs) are being used for cell therapies of patients with liver cirrhosis. A cryopreservation method was established to optimize sourcing of hBTSCs for these clinical programs and that comprises serum-free Kubota's Medium (KM) supplemented with 10% dimethyl sulfoxide (DMSO), ˜3% recombinant human albumin and 0.1% hyaluronans. Cryopreserved versus freshly isolated hBTSCs were similar in vitro with respect to self-replication, stemness traits, and multipotency. They were able to differentiate to functional hepatocytes, cholangiocytes or pancreatic islets, yielding similar levels of secretion of albumin or of glucose-inducible levels of insulin. Cryopreserved versus freshly isolated hBTSCs were equally able to engraft into immunocompromised mice yielding cells with human-specific gene expression and human albumin levels in murine serum that were higher for cryopreserved than for freshly isolated hBTSCs.Type: ApplicationFiled: September 8, 2021Publication date: July 28, 2022Applicants: The University of North Carolina at Chapel Hill, Sapienza Università di RomaInventors: Lola M. Reid, Alvaro Domenico, Vincenzo Cardinale, Eugenio Gaudio, Guido Carpino

Publication number: 20190300849Abstract: Disclosed herein is Brunner's Gland Stem/Progenitor Cells (BGSCs) having phenotypic traits of endodermal stem cells and positive for pluripotency markers, and methods of isolating them from the human duodenum. Moreover, the present disclosure provides that BGSCs are easily isolated from duodenum from human donors, can be expanded in culture or induced to differentiate towards hepatic and pancreatic lineages and could represent a cell source for clinical programs of regenerative medicine.Type: ApplicationFiled: March 28, 2019Publication date: October 3, 2019Applicants: The University of North Carolina at Chapel Hill, Sapienza Universitá di RomaInventors: Guido Carpino, Vincenzo Cardinale, Lola Reid, Domenico Alvaro, Eugenio Gaudio

Patent number: 9750770Abstract: A method of repairing diseased or dysfunctional pancreas or liver is provided. The method involves preparation of a suspension of stem cells and/or progenitor cells such as biliary tree stem cells, hepatic stem cells, pancreatic stem cells or their descendants, committed progenitor cells, from healthy tissue of the patient or of the biliary tree of a non-autologous donor and engrafting the cells into the wall of bile ducts near to the organ to be treated. The graft consists of stem cells or progenitors that are admixed with biomaterials and, optionally, with cytokines and/or native epithelial-mesenchymal cells appropriate for the maturational lineage stage of the cells to be engrafted.Type: GrantFiled: November 9, 2015Date of Patent: September 5, 2017Assignees: The University of North Carolina at Chapel Hill, University of Miami-Diabetes Research Institute, Sapienza Università Di RomaInventors: Lola M. Reid, Yunfang Wang, David A. Gerber, Giacomo Lanzoni, Luca Inverardi, Juan Dominguez-Bendala, Domenico Alvaro, Vincenzo Cardinale, Eugenio Gaudio, Guido Carpino

Patent number: 9488778Abstract: A method for realizing an optical waveguide in a substrate by means of a femtosecond laser system, the waveguide including a birefringence axis tilted by a predetermined angle for at least a segment, is disclosed. The method includes preparing a substrate including a free surface, focusing a femtosecond laser beam into the substrate, in order to induce a refractive index modification of a volume of such substrate around the focal region. The method further includes varying a propagation direction of the femtosecond laser beam to reach a propagation direction describing a predetermined non-vanishing angle with respect to the normal to the free surface of the substrate, and translating the focal region with respect to the substrate, in order to generate the waveguide segment.Type: GrantFiled: April 18, 2014Date of Patent: November 8, 2016Assignees: CONSIGLIO NAZIONALE DELLE RICERCHE, SAPIENZA UNIVERSITA' DI ROMAInventors: Roberto Osellame, Andrea Crespi, Giacomo Corrielli, Fabio Sciarrino
