Abstract:
The present invention concerns the discovery that proteins encoded by a family of vertebrate genes, termed here hedgehog-related genes, comprise morphogenic signals produced by embryonic patterning centers, and are involved in the formation of ordered spatial arrangements of differentiated tissues in vertebrates. The present invention makes available compositions and methods that can be utilized, for example to generate and/or maintain an array of different vertebrate tissue both in vitro and in vivo.
Abstract:
The invention provides a DNA encoding a gene which controls the sex of the embryos of eutherian (Placental) mammals. Nucleic acid fragments, proteins, polypeptides, antibodies and related products and their use in medicine and agriculture are provided. The invention may be used in diagnosis or for controlling the sex of the progeny of commercially important animals.
Abstract:
A polypeptide or protein comprising at least five contiguous amino acid residues in a sequence corresponding to formula (I): VVNGIPTQTTVGX MVSLX YY wherein the internationally recognised 1-letter code is used to represent amino acid residues and X is any naturally occuring L-amino acid residue and X is any amino acid residue, but is preferably an L-leucine residue (L).
Abstract:
The present invention provides a device for the replication of arrays of cell colonies comprising a plate with a large number of small projections projecting therefrom. The projections being formed by removing, preferably by machining, the material between the projections, thus enabling a high density of projections to be achieved.

Abstract:
The present invention relates to nucleotide sequences of vertebrate Delta genes, and amino acid sequences of their encoded proteins, as well as derivatives (e.g., fragments) and analogs thereof. In a specific embodiment, the vertebrate Delta protein is a human protein. The invention further relates to fragments (and derivatives and analogs thereof) of Delta which comprise one or more domains of the Delta protein, including but not limited to the intracellular domain, extracellular domain, DSL domain, domain amino-terminal to the DSL domain, transmembrane region, or one or more EGF-like repeats of a Delta protein, or any combination of the foregoing. Antobidies to Delta, its derivatives and analogs, are additionally provided. Methods of production of the Delta proteins, derivatives and analogs, e.g., by recombinant means, are also provided. Therapeutic and diagnostic methods and pharmaceutical compositions are provided. In specific examples, isolated Delta genes, from Xenopus, chick, mouse, and human, are provided.
Abstract:
