ABSTRACT OF THE INVENTION The present invention relates to an assay and cell lines for determining the biological effects of retinoids. The cell line is derived from a human lung tumour line which is tumorigenic in nude mice and expressed undetectable levels of the .beta. receptor of retinoic acid by introducing in a stable fashion the DNA coding for this receptor. The novel line is non- tumorigenic and grows in culture at a rate which is reduced in the presence of 10-7 M retinoic acid. This line is useful in determining the biological effects of novel retinoids which act in particular by activating RAR.beta..
