Abstract
The present invention provides methods of transdifferentiation of somatic cells, for example, directly converting a somatic cell of a first cell type, e.g., a fibroblast into a somatic cell of a second cell type, are described herein. In particular, the present invention generally relates to methods for converting a somatic cell, e.g., a fibroblast into a motor neuron, e.g., an induced motor neuron (iMN) with characteristics of a typical motor neuron. The present invention also relates to an isolated population comprising induced motor neurons (iMNs), compositions and their use in the treatment of motor neuron diseases such as ALS and SMA. In particular, the present invention relates to direct conversion of a somatic cell to an induced motor neuron (iMN) having motor neuron characteristics by increasing the protein expression of at least three motor-neuron inducing (MN-inducing) factors selected from Lhx3, Ascl1, Brn2, Myt1l, Isl1, Hb9, Ngn2 or NeuroD1 in a somatic cell, e.g., a fibroblast to convert the fibroblast to an induced motor neuron (iMN) which exhibits at least two characteristics of an endogenous motor neuron.
