By Alice de Bernardy Following the fertilisation of an egg by a spermatozoon, from a single totipotent cell develops an entire organism and extraembryonic cells that support its development. Some of these cells later differentiate into gametes, with fertilisation causing yet another round of embryonic development to take place. This is called the germline cycle.1Due toContinue reading “Insights into the germline cycle”

Limb Regeneration – Its History and Future
By Justin Bauer While anuran amphibians (frogs) are unable to regenerate appendages after metamorphosis, urodele (newts, salamanders) amphibians can regenerate limbs in a nerve dependent process that requires the presence of intact peripheral nerves. The regeneration takes place through the formation and growth of a hyper innervated proliferative mass called blastema (Flowers, 2020). In orderContinue reading “Limb Regeneration – Its History and Future”
Diagnosis and Treatment of Hydranencephaly
By Adriana Ramos Calvo Hydranencephaly (HE) is a rare encephaloclastic congenital condition characterized by a membranous sac filled with cerebrospinal fluid replacing a big percentage of the corpus striatum and cerebral hemispheres, while normally not affecting the midbrain (Pant, Kaur and De, 1970). It is a relatively rare and mostly isolated disease since it isContinue reading “Diagnosis and Treatment of Hydranencephaly”
Bioelectricity: The Missing Link in Regeneration
By Charlotte Hutchings Regeneration occurs on several scales with species differing in their capacity to regenerate tissues, organs, and limbs (Maden, 2018). One group commonly used to study regeneration is the Planarian worms. Many planarians have the remarkable ability to regenerate their entire body after being split in two, primarily through the activity of pluripotentContinue reading “Bioelectricity: The Missing Link in Regeneration”
The embryology of conjoined twins
By Anastasia Alenova Occurring once in 50,000 births, conjoined twins are a rare and abnormal form of monozygotic twins. Conjoined twins are classified into seven types based on their site of attachment, followed by the suffix “pagus” which means “fixed” in Greek (O’Neill et al., 1988; Mian et al., 2017). The fascination for conjoined twinsContinue reading “The embryology of conjoined twins”
The children who can see underwater
By Safiya Aldris The Mergui Archipelago, a group of around 800 islands in the Andaman sea, is home to the Moken. They are a semi-nomadic Austronesian people living a hunter-gatherer lifestyle at sea, though this way of life is increasingly under threat (Survival, n.d.). The children of these small Moken tribes spend much of theirContinue reading “The children who can see underwater”
