The most widely accepted definition of a dwarf is a person with an adult height of less than 4 feet 10 inches (147cm). In older popular and medical usage, any type of marked human smallness could also be termed dwarfism. People who are affected by dwarfism are often referred to as "little people".

New trial shows oral therapy increases growth in children with achondroplasia

New findings from a trial conducted at Children's Hospital Colorado (Children's Colorado) and University of Colorado (CU) Anschutz School of Medicine demonstrate significantly increased growth rates in children with achondroplasia, the most common form of dwarfism.

New mouse model uncovers achondroplasia's cellular growth plate dysregulation

Achondroplasia, also known as short-limb dwarfism, is associated with neurological symptoms and complications due to narrowing of the skeletal structures surrounding the spinal cord.

Hypertrophic chondrocytes play a crucial role in bone growth and repair

Normal, regulated growth of skeletal bones is a crucial part of the growth of mammals. This is a complex process involving the growth of cartilaginous cells or chondrocytes, their transformation into bone-building cells or osteoblasts, and the formation of new blood vessels to supply the newly formed bone tissue.
