Cellosaurus Walvax-2 (CVCL_5J50)

[Text version]
Cell line name Walvax-2
Synonyms WALVAX-2; WALVAX 2; Walvax 2; WALVAX2; Walvax2
Accession CVCL_5J50
Resource Identification Initiative To cite this cell line use: Walvax-2 (RRID:CVCL_5J50)
Comments Group: Patented cell line.
Group: Vaccine production cell line.
Registration: International Depositary Authority, China Center for Type Culture Collection; CCTCC C201055.
Senescence: Maintains excellent capabilities for growth and proliferation until PDL 50 (maximum PDL is 58).
Doubling time: 39-41 hours (Note=At 28th passage), 40-42 hours (Note=At 38th passage), 57-62 hours (Note=At 48th passage) (PubMed=25803132).
Anecdotal: Is causing an outrage in some pro-lifer circles because it is a cell line originating from an aborted (for medical reasons) 3-month old female fetus.
Derived from site: In situ; Fetal lung; UBERON=UBERON_0005597.
Cell type: Fibroblast of lung; CL=CL_0002553.
