Neglected Biological Features in Cnidarians Self-Nonself Recognition
Cnidarian taxa, currently of the most morphologically simplest extant metazoans, exhibit many salient properties of innate immunity that are shared by most Animalia. One hallmark constituent of immunity exhibi...

Stem Cells: Autonomy Interactors that Emerge as Causal Agents and Legitimate Units of Selection
Can stem cells be defined as legitimate units of selection (UOS)? Here I review traits of hallmark stem cells (many of which are manifested in marine organisms), which collectively reveal that some types of st...

Stem Cells in Aquatic Invertebrates: Common Premises and Emerging Unique Themes
The remarkable ability to generate an embryo from a single fertilized oocyte and to regenerate tissues that are injured or going through natural physiological turnover, is the direct result of stem cells, natu...

Stem Cells, Chimerism and Tolerance: Lessons from Mammals and Ascidians
Chimerism is the presence of cells derived from more than one individual in a given individual. This phenomenon has been detected in a wide variety of multicellular organisms, including vertebrates. In mammals...

Molecular Characterization of Metallothionein- and Cytochrome P4501A-CDNAS of Sparus aurata and Their Use for Detecting Pollution along the Mediterranean Coast of Israel
Members of the fish family Sparidae are abundant in various continental shelf habitats along the Mediterranean, including relatively clean and polluted regions. Fish Metallothionein (MT) and cytochrome P4501A ...

Retreat Growth in the Ascidian Botryllus Schlosseri: A Consequence of Nonself Recognition
In the genus Botryllus fusion between genetically distinct individuals is controlled by a single genetic locus (or haplotype) with multiple codominantly expressed alleles. Colonies which do not share an allele at...

Speculations on the Relationships of Two Botryllus Allo-Recognition Reactions—Colony Specificity and Resorption—To Vertebrate Histocompatibility
The objective of this essay is to consider functions of the vertebrate major histocompatibility complex (MHC), especially in comparison to allorecognition in colonial tunicates. Elsewhere Burnet (1971), and ou...
