Abstract: | Summary A lymphoma cell line (MCC) was derived from an abdominal mass from a 13-yr-old castrated male cat. The cells resemble natural
killer precursor cells, have membrane-bound granules, and are positive for chloroacetate esterase, α-naphthyl butyrate esterase,
and tartrate-resistant acid phosphatase activities. The MCC cells are negative for rearranged feline T-cell receptor genes,
negative for feline T-cytotoxic antigen, Ia, and surface μ, τ, and lambda chains and do not form E-rosettes. The MCC cell
line is negative for the feline leukemia virus (FeLV); e.g., negative for exogenous FeLV (exU3) sequences, negative for cytoplasmic
and surface FeLV major core protein of 27 000 daltons (p27) by indirect, immunofluorescence assay, negative for helper FeLV
by clone 81 assay, and negative for release of soluble FeLV p27 by enzyme-linked immunosorbent assay. Electron microscopy
reveals budding type C retrovirus particles and MCC cells react with anti-RD-114 (anti-endogenous feline retrovirus) reference
serum. After in vitro infection, MCC replicate FeLV readily, but replication is noncytopathic.
