Multiple cryoinjuries modulate the efficiency of zebrafish heart regeneration

Bise, Thomas ; Sallin, Pauline ; Pfefferli, Catherine ; Jaźwińska, Anna

In: Scientific Reports, 2020, vol. 10, no. 1, p. 11551

Zebrafish can regenerate their damaged hearts throughout their lifespan. It is, however, unknown, whether regeneration remains effective when challenged with successive cycles of cardiac damage in the same animals. Here, we assessed ventricular restoration after two, three and six cryoinjuries interspaced by recovery periods. Using transgenic cell-lineage tracing analysis, we demonstrated...

Platelet transforming growth factor-β1 induces liver sinusoidal endothelial cells to secrete interleukin-6

Balaphas, Alexandre ; Meyer, Jeremy ; Perozzo, Remo ; Zeisser-Labouebe, Magali ; Berndt, Sarah ; Turzi, Antoine ; Fontana, Pierre ; Scapozza, Leonardo ; Gonelle-Gispert, Carmen ; Bühler, Leo H.

In: Cells, 2020, vol. 9, no. 5, p. 1311

The roles and interactions of platelets and liver sinusoidal endothelial cells in liver regeneration are unclear, and the trigger that initiates hepatocyte proliferation is unknown. We aimed to identify the key factors released by activated platelets that induce liver sinusoidal endothelial cells to produce interleukin-6 (IL-6), a cytokine implicated in the early phase of liver regeneration....

Platelet interactions with liver sinusoidal endothelial cells and hepatic stellate cells lead to hepatocyte proliferation

Meyer, Jeremy ; Balaphas, Alexandre ; Fontana, Pierre ; Morel, Philippe ; Robson, Simon C. ; Sadoul, Karin ; Gonelle-Gispert, Carmen ; Bühler, Léo

In: Cells, 2020, vol. 9, no. 5, p. 1243

Background: Platelets were postulated to constitute the trigger of liver regeneration. The aim of this study was to dissect the cellular interactions between the various liver cells involved in liver regeneration and to clarify the role of platelets. (2) Methods: Primary mouse liver sinusoidal endothelial cells (LSECs) were co-incubated with increasing numbers of resting platelets, activated...

Towards deciphering variations of heart regeneration in fish

Jaźwińska, Anna ; Blanchoud, Simon

In: Current Opinion in Physiology, 2020, vol. 14, p. 21–26

Among adult vertebrates, the zebrafish presents the rather exceptional capacity to efficiently regenerate its heart after injury. This bony fish has thus become a leading genetic model organism to elucidate the natural mechanisms of successful cardiac restoration. Given its potential biomedical significance, parallel analyses between zebrafish and mammals are aiming at the identification of...

Zebrafish fin regeneration involves transient serotonin synthesis

König, Désirée ; Jaźwińska, Anna

In: Wound Repair and Regeneration, 2019, p. wrr.12719

The zebrafish is a vertebrate organism capable of regenerating many of its organs. Notably, it can undergo epimorphic regeneration of its fins after amputation. This process occurs through the formation of a wound epithelium and the dedifferentiation of mesenchymal and bone‐forming cells, which form a proliferative blastema. Here, we report that the entry into the regenerative process...

Ciliary neurotrophic factor stimulates cardioprotection and the proliferative activity in the adult zebrafish heart

Bise, Thomas ; de Preux Charles, Anne-Sophie ; Jaźwińska, Anna

In: npj Regenerative Medicine, 2019, vol. 4, no. 1, p. 2

Unlike mammals, adult zebrafish can regenerate their hearts after injury via proliferation of cardiomyocytes. The cell-cycle entry of zebrafish cardiac cells can also be stimulated through preconditioning by thoracotomy, a chest incision without myocardial damage. To identify effector genes of heart preconditioning, we performed transcriptome analysis of ventricles from thoracotomized...
