Cardiac myofibril induction
Methods and products for altering or promoting the development of heart tissue are disclosed. The methods include the use of nucleic acids of cardiogenic inducing factor for treating a subject having heart disease.
1. A method for rescuing a congenitally defective heart of an embryonic axolotl, the method comprising: providing an embryonic axolotl comprising a recessive lethal cardiac mutation in gene “c”, wherein said gene “c” mutation causes development of congenitally defective heart; and
introducing into the heart of said embryonic axolotl a composition comprising a cardiogenic inducing RNA nucleic acid (CIR); wherein said CIR is selected from the group consisting of CIR 1 and CIR 2; and wherein said introducing of said composition rescues the heart of said embryonic axolotl from developing into said congenitally defective heart.
2. The method of claim 1 , wherein the composition is comprised in and expressed by a cell, and said introducing occurs by injection of the cell into said heart of said embryonic axolotl.
3. The method of claim 1 , wherein said introducing occurs by direct injection of the composition into the heart of said embryonic axolotl.
