The Ontogeny of Skin [PDF]

open access: yesAdvances in Wound Care, 2014
Significance: During gestation, fetal skin progresses from a single layer derived from ectoderm to a complex, multi-layer tissue with the stratum corneum (SC) as the outermost layer. Innate immunity is a conferred complex process involving a balance of pro- and anti-inflammatory cytokines, structural proteins, and specific antigen-presenting cells. The

Swimming abilities of temperate pelagic fish larvae prove that they may control their dispersion in coastal areas [PDF]

open access: yes, 2019
The Sense Acuity and Behavioral (SAAB) Hypothesis proposes that the swimming capabilities and sensorial acuity of temperate fish larvae allows them to find and swim towards coastal nursery areas, which are crucial for their recruitment. To gather further

The development of the Silurian trilobite Aulacopleura koninckii reconstructed by applying inferred growth and segmentation dynamics: A case study in paleo-evo-devo [PDF]

open access: yes, 2017
Fossilized growth series provide rare glimpses into the development of ancient organisms, illustrating descriptively how size and shape changed through ontogeny.

Ontogeny of neuroembryology [PDF]

open access: yesThe Journal of Neuroscience, 1988
This essay commemorates the 100th anniversary of the birth of neuroembryology. One cannot, of course, ascribe the beginning of a branch of science to a single year, but the years between 1885 and 1890 saw major publications by the German anatomist Wilhelm His (1831–1904) and the Spanish histologist S.

Ontogeny of Myeloid Cells [PDF]

open access: yesFrontiers in Immunology, 2014
Granulocytes, monocytes, macrophages, and dendritic cells (DCs) represent a subgroup of leukocytes, collectively called myeloid cells. During the embryonic development of mammalians, myelopoiesis occurs in a stepwise fashion that begins in the yolk sac and ends up in the bone marrow (BM).

Ontogenetic scaling patterns and functional anatomy of the pelvic limb musculature in emus (Dromaius novaehollandiae) [PDF]

open access: yes, 2014
Emus (Dromaius novaehollandiae) are exclusively terrestrial, bipedal and cursorial ratites with some similar biomechanical characteristics to humans. Their growth rates are impressive, as their body mass increases eighty-fold from hatching to adulthood ...

On growth and form of irregular coiled-shell of a terrestrial snail: Plectostoma concinnum (Fulton, 1901) (Mollusca: Caenogastropoda: Diplommatinidae) [PDF]

open access: yesPeerJ, 2014
The molluscan shell can be viewed as a petrified representation of the organism’s ontogeny and thus can be used as a record of changes in form during growth.

Ontogeny of the Immune Response [PDF]

open access: bronzeThe Journal of Immunology, 1968
Summary Germfree, immunologically virgin piglets were used to study the ontogenic development of immunoglobulins. In the true primary immune response, the first antibody synthesized was 19 S γG-immunoglobulin which was antigenically identical to the late immune 7 S γG-immunoglobulin but distinct from 19 S γM.
