In vitro modeling of amyotrophic lateral sclerosis with induced pluripotent stem cell technology-derived cell line ORIONi002-A.

We present here a new iPS cell line for modeling sporadic form of ALS. Cell line was generated by reprogramming skin fibroblasts isolated with explant culture technology from skin biopsy, donated by ALS patient. For reprogramming, polycistronic self-replicating RNA vector was used and derived iPS cells were characterized by immunocytochemistry and FACS (pluripotent factors expression), karyotyping, STR fingerprinting analysis and in vitro differentiation assay. New cell line showed normal (46, XY) karyotype and differentiated in vitro into cells from three germ layers. STR analysis proved the origin and originality of the cell line.

Establishment of PANDA - a new human pancreatic ductal adenocarcinoma cell line with 3D cell culture technology.

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive type of malignancy with one of the worst prognoses amongst any type of cancer. Surgery is applicable only to the limited number of patients with locally resectable tumors and currently represents the only curative treatment option. Treatment with chemotherapy and radiotherapy can only extend patient survival. Despite advances in conventional therapies, the five-year survival of PDAC remained largely unchanged. New in vitro and in vivo models are therefore urgently needed to investigate this type of cancer. Here, we present the establishment and characterization of a novel pancreatic cancer cell line, isolated from a patient with PDAC. Cell line abbreviated as PANDA (PANncreatic Ductal Adenocarcinoma) was established with an optimized 3D culture protocol published previously by our group. The new cancer cell line "PANDA" represents a novel in vitro approach for PDAC cancer research and new therapy testing.

Generation of ORIONi001-A induced pluripotent stem cell line for in vitro modeling of sporadic form of amyotrophic lateral sclerosis.

We generated new in vitro model for sporadic form of amyotrophic lateral sclerosis by reprogramming isolated skin fibroblasts into iPSCs. Fibroblasts were reprogrammed with commercially available synthetic polycistronic, self-replicating RNA vector. As verified by FISH, an early passages of a new iPSC line showed mosaic karyotype (cells with normal and abnormal karyotype 46,XY,t(2;14)(q13;p12) were present), while late passages contained only cells with abnormal karyotype. New iPSCs differentiated into all three germ layers and formed a teratoma in nude mice. Our iPSC line represents a new model for therapy testing and drug development in the field of ALS research.
