AN INJECTION of bone marrow cells could patch up ailing hearts, last week’s
conference heard. Researchers have had promising results with the technique in
mice and pigs.
During a heart attack, muscle cells in the affected area are starved of
oxygen and die. Depending on the extent of the damage, the remaining muscle can
become overstrained and ultimately the heart may fail.
Researchers at Johns Hopkins University and the biotech company Osiris
Therapeutics, both in Baltimore, suspected that stem cells from bone marrow
might be able to repair such damage. Normally, these stem cells give rise to
blood cells, but…
