" Mesenchymal stromal cells loaded with Paclitaxel home glioblastoma vasculature and inhibit tumor growth” of AIRC ( Associazione Italiana per la Ricerca sul Cancro) ( 2013-2016) Some notes on research activity particularly related to hematotoxicity The experience of Dr Augusto Pessina in the field of hematotoxicity originated in the years 1970 with studies concerning the relation between the neoplastic growth and the haematopoietic disorders observed in tumor bearing mice. He developed specific “in vitro” techniques for studying the effect exerted by factors produced by tumor cells on the proliferation and differentiation of myeloid precursors and in his laboratory were isolated cytokines active on the haematopoietic progenitors (Int. J. Immunopharmacol. 7,549,1985; Blut,55,499,1987). At the first UICC training course organized in Amsterdam on 1975 had as teacher Donald Melcalf (who is considered the pioneer of the “in vitro” studies on proliferation and differentiation of haematopoietic progenitors) and the possibility to improve the techniques for assessing the "in vitro" growth of granulocytemacrophage committed cells (GM-CFU). Dr. Pessina has been involved five years (1976-1981)in an international project at the Hospital of Desio (Milan ,Italy) for studying the haematotoxic effect of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on the immune system of children accidentally exposed to the toxic in the area of Seveso ( ICMESA accident). Since 1981 he runs a Laboratory of Cell Culture at the Institute of Microbiology (Milan) and his researches have been continued on the relationship between tumor growth and the production of cytokines ( CSFs) involved in the proliferation- differentiation of pluripotent stem cells ( CFU-s) and committed progenitors ( CFU-C) in haematopoiesis ( J. Cancer Res.Clin. Oncol.,102,235,1982; Oncology 39,391,1982; J.Natl.Cancer Inst.,¸76,1095,1986). In his laboratory have been established twi new cell lines: a stromal cell line obtained from murine bone marrow adherent cells (SR-4987) , ( Cytotechnology 8,93,1992 ) available by ATCC (CRL-2028) and a subclone of WEHI-3B leukemia cells resistant to ciprofloxacin ( Cancer J.,6,291,1993) due to a mutation of topoisomerase II. By using SR-4987 cells has been standardized a new "in vitro" method for testing FGFs in biological samples and developed an “in vitro” model to investigate the role of stromal cells in the modulation of drug induced hematotoxicity (Life Sci.,65,513,1999). Researches of the response of different cellular models the biological effects of microbial toxins demonstrated that the proliferative block exerted by Cholera Toxin may be dependent or not to the cAMP accumulation and that there are membrane ganglioside with different affinity to CT ad capacity to transduce the signal. A stable mutant of a leukemia cell line (WEHI-3B) has been established by Dr Pessina which lacks of the Gal-GalNac-GM1b ganglioside that is a very important functional receptor in WEHI-3b cells ( Cell .Mol.Biol.,44,933-940,1998. Mol.Cell.Biochem,152,103-112,1995 Mol.Cell Biochem. 233,19-26, 2002) By using GM-CFU techniques Dr Pessina studied the effect of topoisomerase inhibitors, antibiotics and microbial toxins on different animal cell models ( J.Antimicrob. Chemother., 24,203,1989; Biochim .Bioph. Acta,1013,206,1989 ; Mol. Cell Biochem.,152,1995). Since 1994 he managed EC contracts concerning the development of alternative methods for hematototoxicity testing and coordinated projects of prevalidation and validation of standard operating procedure based on the use of multipotent stem cells as progenitors of granulocyte-macrophages (GMCFU) , megakaryocytes (Mk-CFU) and erythrocytes (CFU-E). Based on these results ( Toxicological Sciences , 75,355-367,2003 ) the ECVAM Scientific Advisory Committee (ESAC) on 2006 unanimously endorsed the CFU-GM assay for predicting acute neutropenia in humans. Recently a study has been conducted to prevalidate the GM-CFU assay with frozen bone marrow cells of rat that can contribute to REACH programme ( Altern.To Lab.Animals 37: 417-425,2009. Altern.To Lab.Animals 38:105-117,2010). Since 2004 the cell culture laboratory of Dr Pessina is involved in studies on the therapeutic potential of stem cells and on assays to assess their safety with a particular attention to the microbiological risks (BBRC, 323:315-322,2004, Crit.Rev.Microbiol, 34:1-12,2008,Transpl Infect Dis .11 : 491-496,2009 ;,Cell Biol. Int. 34:783-790,2010). More recent his group have indicated that MSCs can be used as drug carrier. By using a cancer drug ( Paclitaxel) has been demonstrated that human MSCs are able to uptake and release the drug and that PTX loaded MSCs produced a dramatic inhibition of tumor growth both in vitro and in vivo. PLoS ONE 6(12): e28321. doi:10.1371/journal.pone.0028321. In recent paper his laboratori demonstrated that drugs can be released by mesenchymal stem cells into microvesicles/exosomes opening new possible biotechnology application for the production of more bioavailable molecules able to support new therapeutic approaches.
