I am just adding in the Cellosaurus the very detailed info in the very recent review paper:

"Comprehensive Genetic Characterization of Human Thyroid Cancer Cell Lines: A Validated Panel for Preclinical Studies"

DOI=10.1158/1078-0432.CCR-18-2953

and in term of PTC with a BRAF V600E I noted:

CUTC5:

https://web.expasy.org/cellosaurus/CVCL_W916

CUTC60:

https://web.expasy.org/cellosaurus/CVCL_VM61

Both cell lines have just been published in:

https://www.ncbi.nlm.nih.gov/pubmed/30733375

IHH-4:

https://web.expasy.org/cellosaurus/CVCL_2960

Available from JCRB

K1:

https://web.expasy.org/cellosaurus/CVCL_2537

Which is in fact GLAG-66 but which does not seem to be distributed.

LAM1:

https://web.expasy.org/cellosaurus/CVCL_W912

LAM136:

https://web.expasy.org/cellosaurus/CVCL_RP38

MDA-T120:

https://web.expasy.org/cellosaurus/CVCL_QW85

MDA-T32

https://web.expasy.org/cellosaurus/CVCL_W913

MDA-T41

https://web.expasy.org/cellosaurus/CVCL_W914

MDA-T85

https://web.expasy.org/cellosaurus/CVCL_QW84

All four MDA-Txxx cell lines are distributed by ATCC
