  • The limbs had evolved from fins; during the transition, our back-boned ancestors lost rows of rigid fibers, called actinotrichia, that provide structural support and guide fin development.

  • "Their conclusions are really intriguing and well justified." showing the array of actinotrichia.

  • J. Zhang et al. "Loss of fish actinotrichia proteins and the fin-to-limb transition,"

    News from The Scientist

  • "The loss of actinotrichia may have been conducive to ancestral, primitive tetrapods having limbs resembling cases of polydactyly," said Akimenko.

    News from The Scientist

  • And without actinotrichia, there was no regional recruitment of mesenchymal cells, the precursors to the bones of the fin exoskeleton.

    News from The Scientist

  • But when both were silenced, major changes occurred: First, actinotrichia didn't form.

    News from The Scientist

  • "This the first time that anyone has really looked at genes underlying actinotrichia," said Mabee.

    News from The Scientist

  • The gene expression pattern suggested the proteins are structural components of actinotrichia

    News from The Scientist

  • In contrast to the pectoral fin bud of teleost fish, the mouse limb bud does not contain actinotrichia.

    News from The Scientist

  • When they disrupted the two genes in the regenerating fins of adults in the same way, they found that the distribution of actinotrichia was affected.
