Similarly AAV2 mediated in vivo co-transfection of BMP-7 and SOX-9 could enhance the expression of collagen II and proteoglycan, and significantly improve the height of degenerative rabbit discs [ 50].
In 1535, Henry VIII passed the Breed of Horses Act aimed at improving the height and strength of horses; no stallion under and no mare under 13 hands (52 inches, 132 cm) was permitted to run out on common land, or to run wild, and no two-year-old colt under 11.2 hands (46 inches, 117 cm) was allowed to run out in any area with mares.
