Abstract: Methods for treating diseased or damaged tissue in a subject are disclosed, involving administering to said subject at a site wherein diseased or damaged tissue occurs, cells of a type(s) normally found in healthy tissue corresponding to the diseased or damaged tissue, and/or suitable progenitor cells thereof, in association with bioresorbable beads or particles and optionally a gel and/or gel-forming substance. Where the cells an/or suitable progenitor cells thereof are chondrocytes, embryonic stem cells and/or bone marrow stromal cells, the methods of the invention are suitable for treating, for example, articular cartilage degeneration associated with primary osteoarthritis.

Abstract: The invention relates to a method for producing hydroxylated triple helical proteins in yeast host cells by introducing to a suitable yeast host cell, DNA sequences encoding the triple helical protein as well as prolyl 4-hydroxylase (PH4), in a manner wherein the introduced DNA sequences are replicated, stably retained and segregated by the yeast host cells.

Abstract: A method for producing a hydroxylated triple helical protein is disclosed, as well as a yeast host cell used in the method. The method comprises culturing a yeast host cell comprising: (1) a first DNA molecule comprising a DNA sequence encoding P4H&agr; subunit operably linked to a promoter functional in the yeast host cell, (2) a second DNA molecule comprising a DNA sequence encoding P4H&agr; subunit operably linked to a promoter functional in the yeast host cell, and (3) a third DNA molecule comprising a DNA sequence encoding a polypeptide or peptide operably linked to a promoter functional in the yeast host cell, wherein the polypeptide or peptide is one which, when hydroxylated, forms the hydroxylated triple helical protein; and wherein during culturing, each of the first DNA molecule, the second DNA molecule and the third DNA molecule are replicated, stably retained and segregated.
