The information theory of aging

YR Lu, X Tian, DA Sinclair - Nature aging, 2023‏ - nature.com
Abstract Information storage and retrieval is essential for all life. In biology, information is
primarily stored in two distinct ways: the genome, comprising nucleic acids, acts as a …

Stem cell systems and regeneration in planaria

JC Rink - Development genes and evolution, 2013‏ - Springer
Planarians are members of the Platyhelminthes (flatworms). These animals have evolved a
remarkable stem cell system. A single pluripotent adult stem cell type (“neoblast”) gives rise …

Cell type atlas and lineage tree of a whole complex animal by single-cell transcriptomics

Single-cell analysis reveals functionally distinct classes within the planarian stem cell compartment

JC Van Wolfswinkel, DE Wagner, PW Reddien - Cell stem cell, 2014‏ - cell.com
Planarians are flatworms capable of regenerating any missing body region. This capacity is
mediated by neoblasts, a proliferative cell population that contains pluripotent stem cells …

Pluripotent, germ cell competent adult stem cells underlie cnidarian regenerative ability and clonal growth

Á Varley, HR Horkan, ET McMahon, G Krasovec… - Current Biology, 2023‏ - cell.com
In most animals, pluripotency is irreversibly lost post gastrulation. By this stage, all
embryonic cells have already committed either to one of the somatic lineages (ectoderm …

Annelid adult cell type diversity and their pluripotent cellular origins

P Álvarez-Campos, H García-Castro, E Emili… - Nature …, 2024‏ - nature.com
Many annelids can regenerate missing body parts or reproduce asexually, generating all
cell types in adult stages. However, the putative adult stem cell populations involved in these …

Aging and longevity in the simplest animals and the quest for immortality

RS Petralia, MP Mattson, PJ Yao - Ageing research reviews, 2014‏ - Elsevier
Here we review the examples of great longevity and potential immortality in the earliest
animal types and contrast and compare these to humans and other higher animals. We start …
