TL;DR

Abstract
A monoclonal antibody derived by fusion of mouse myeloma cells with spleen cells from a mouse immunized with F9 teratocarcinoma cells is described. This antibody, which reacts with embryonal carcinoma cells of mouse and human origin and with some preimplantation stage mouse embryos, defines an embryonic stage-specific antigen. This stage-specific antigen (SSEA-1) is first detected on blastomeres of 8-cell stage embryos. Trophectodermal cells are transitorily positive; however, each cell in the inner cell mass eventually expresses this antigen.

The derivation of a number of tissue culture cell lines which secrete anti-sheep red blood cell (SRBC) antibodies is described here, made by fusion of a mouse myeloma and mouse spleen cells from an immunised donor.

Evidence can be obtained which suggests that mating may be followed by segregation in mice, and when two clonal lines of mouse fibroblasts are grown together for 4 days, hybrid cells can be detected by selective conditions.

FUSION between myeloma cells and spleen cells from immunised donors has been shown to be a successful method of deriving homogeneous anti-SRBC (anti-sheep red blood cell) and anti-TNP antibodies.

The results suggest that the mouse blastocyst is not permeable for certain antibodies, and the inner cell masses can easily be separated from the remnants of trophoblastic cells and are then able to grow and differentiate in vitro.

The embryonal carcinoma enzyme resembles the enzymes from kidney and placenta in kinetics of thermal inactivation and sensitivity to the inhibitor L-phenylalanine, but is distinguishable from the alkaline phosphatases of liver and intestine.

The results are consistent with the concept, deveolped from work on other cell types, that plasminogen activator may represent a generalized mechanism for tissue remodeling and cell migration.

The cytotoxicity test to sperm with antisera directed against a number of systems of mouse alloantigens, but none of these has given a positive reaction with sperm, which is not surprising because these are all “differentiation antigens” expressed primarily on lymphoid cells.

A set of monoclonal antibodies derived by fusing P3-NS1/1-Ag4-1 myeloma cells with spleen cells from a rat immunized with mouse spleen were screened for activity against a tumor cell panel and one was found to react only with mouse embryonal carcinoma cells and no other tumor cell type tested.

The tissue distribution of HPRT-deficient cells suggests that selection against them is particularly strong in blood of the mosaic mice, which supports the expectation that afflicted F(1) male mice that might be obtained from mutant germ cells can serve as a model of the human disease.

A cell-surface antigen common to mouse primitive teratocarcinoma cells, morulae, and sperm has been shown by serological methods to be specified by a wild-type T-locus gene whose mutant form is lethal in homozygotes at the morula stage.

Results from indirect immunofluorescence, cytotoxicity, and culturing experiments lead to two major conclusions: anti-blastocyst serum detects a group of cell surface molecules whose expression is embryo- specific, stage-specific, and whose unaltered presence is required for preimplantation development in vitro.

It is concluded that presence of growing tumors in the mouse is not necessary for the production of anti-SV40 T antigen antibodies but that helper thymus-derived cells are essential for the humoral response.
