TORONTO - Gordie Howe's son Mark says his father is doing well after receiving a second experimental stem cell transplant this week.

The 87-year-old hockey legend was treated Monday at the same Mexican clinic where he underwent an initial injection of stem cells in his spine in December, following a debilitating stroke last October.

Mark says his brother Murray, who's a doctor, took Howe to the Tijuana clinic, where their dad got "a little boost" from the therapy.

Mark says they are flying today to Toledo, Ohio, where Howe will stay with Murray and his wife after having lived with his daughter Cathy Purnell in Lubbock,Texas.

, the family called Howe's improvement "miraculous." He was able to walk again and his ability to speak improved.

The October stroke -- his second -- had left the former NHL great without the use of his right arm and leg and had caused his speech to slur.
