abstract = {Osteosarcoma is an aggressive bone malignancy with high
metastatic potential to the lungs. CTCs, as seeds of
metastasis, play an important role in the spread of this
cancer, and, therefore, their isolation, culture, and gene
expression analysis promises valuable insights into the
progression and metastatic cascade of osteosarcoma. The aim
of this study was to isolate and culture CTCs from
osteosarcoma-bearing mice and compare their migration,
radioresistance, and gene expression with their parental
cell line.CTCs from LM8-inoculated mice were isolated and
cultured. The gene expression of the CTC-derived cell lines
was then compared to the parental cell line. Furthermore, a
Transwell assay, a clonogenic assay after irradiation, and
immunohistochemical stainings were used to compare the
CTC-derived cell lines with the parental cell line.The
CTC-derived cell lines differed significantly in gene
expression from their parental cell line. 361 differentially
expressed genes were identified, among which GO and KEGG
analysis revealed major differences in the expression of
genes related to antigen processing and presentation and
extracellular matrix constituents. In addition, the
CTC-derived cell lines were observed to have a higher
migratory capacity and comparable radioresistance compared
to the parental cell line. CD44 expression was found to be
conserved in CTC-derived cell lines.This study provides a
comparison between CTC-derived and their parental cell lines
in terms of gene expression, migration, and radioresistance.
Our findings allow for further research in the field of
osteosarcoma CTCs and their generation. Furthermore, the
identified DEGs between CTCs and their parental cell line
can serve as a reference point for targeted therapies
against osteosarcoma CTCs.},
