Abstract: Reprogramming allows the “conversion” of any mature or somatic cell of the human or animal body into a pluripotent stem cell. Reprogramming can be performed through the introduction of exogenous factors, usually transcription factors, into the mature cell. This process allows the production of induced pluripotent stem cells without the use of embryos, with the advantage that they can be produced from an individual to return/re-implant to the same individual. The inventors have developed a method of transient expression of exogenous reprogramming factors using a transient vector, wherein the vector is a closed linear DNA. Surprisingly, pluripotent stem cells developed in this manner are stable and closer in phenotype to natural stem cells such as ESCs.

Abstract: The invention describes a method for selecting a polypeptide ligand having a desired level of specificity for a target, wherein the polypeptide ligand comprises a polypeptide comprising at least three reactive groups, separated by at least two loop sequences, and a molecular scaffold which forms covalent bonds with the reactive groups of the polypeptide such that at least two polypeptide loops are formed on the molecular scaffold, comprising (i) screening at least two different sets of polypeptide ligands against the target, and selecting one or more ligands from each library which interact with the target; (ii) comparing the activity of the selected ligands with one or more paralogues or orthologues of the target; and (iii) further selecting one or more ligands according to their activity towards said one or more paralogues or orthologues; wherein said two or more different sets of ligands differ in the length of the polypeptide loops formed on the molecular scaffold.

Abstract: The invention relates to a method for providing a multispecific peptide ligand comprising a polypeptide covalently linked to a molecular scaffold at three or more amino acid residues and capable of binding to two or more separate targets, comprising the steps of: (a) providing a first repertoire of polypeptides, each polypeptide comprising two or more reactive groups capable of covalent linkage to a molecular scaffold, and at least one loop which comprises a sequence of two or more amino acids subtended between two of said reactive groups; (b) providing a second repertoire of polypeptides as described in (a); (c) joining at least one loop of one or more members of the first repertoire to at least one loop of one or more members of the second repertoire to form at least one polypeptide comprising two loops, and (d) conjugating the composite polypeptide(s) to a molecular scaffold at at least three amino acid positions.
