(A, B) (B) A 5 μm projection of tg(prox1a:kalTA4; UAS:GFP) embryos stained for 2F11 and DAPI at 80 hpf (A) and 96 hpf (B). White arrowheads indicate GFP+ BEC nuclei, and yellow arrows highlight GFP− endothelial cells. (N = 2, n = 8 livers). (C) A 10 μm projection of an adult liver section stained for Prox1 (magenta) and Anxa4 (green), white arrowheads indicate Prox1+ BEC nuclei, and yellow arrows highlight Prox1− endothelial cells. The Prox1 signal was filtered using a median filter with a 3-pixel kernel for better visualisation. (N = 2, n = 6 sections). (D) Schematic representation of the stepwise activation times of the fraeppli transgene. (E) PCR amplification of the mKate2 locus in individual embryos at 26 hpf or 33 hpf upon heat shock–mediated recombination at 26 hpf. (N = 2, n ≥ 16 embryos). (F) Distribution of the number of FRaeppli recombined loci per embryo upon heat shock at 26 hpf determined by PCR amplification of the recombined transgene. Band intensities at 26 hpf were about 4–6 times lower compared to later time points (N = 2, n ≥ 11 embryos). (G) Quantification of total liver cell numbers, encompassing hepatocytes and BECs, during development (N = 4, n ≥ 12 livers). Different shape data points indicate different experiments. (H, I) fraeppli-nls embryo activated by phiC31 mRNA injection showing only TagBFP and mTFP1 expression at 60 hpf (H), and expression of all 4 FRaeppli FPs at 120 hpf (n = 4 livers) (I). Temporal FP colour detection reflects the individual protein maturation times and depends on the strength of the respective Gal4-driver [32]. (J) Timelapse of TagBFP+ and mTFP1+ cells using spectral imaging of the liver upon heat shock induction at 9 hpf (N = 2, n = 3 livers). Some neighbouring cells stay close together (magenta arrow), while others move up to 20 μm apart (green arrows). (K, L) fraeppli-nls embryo reimaged at 60 hpf, 72 hpf, and 100 hpf. In sparse recombined embryos (K), not all 4 FRaeppli colours are expressed at 100 hpf and an individual labelled cell divides 2 times (n = 2 livers). In highly recombined embryos expression of all 4 colours is visible at 100 hpf (n = 10 livers). (Total N = 2, n = 18 livers). The numerical values that were used to generate the graphs in (F, G) can be found in S1 Data., Peer reviewed

To meet the physiological demands of the body, organs need to establish a functional tissue architecture and adequate size as the embryo develops to adulthood. In the liver, uni- and bipotent progenitor differentiation into hepatocytes and biliary epithelial cells (BECs), and their relative proportions, comprise the functional architecture. Yet, the contribution of individual liver progenitors at the organ level to both fates, and their specific proportion, is unresolved. Combining mathematical modelling with organ-wide, multispectral FRaeppli-NLS lineage tracing in zebrafish, we demonstrate that a precise BEC-to-hepatocyte ratio is established (i) fast, (ii) solely by heterogeneous lineage decisions from uni- and bipotent progenitors, and (iii) independent of subsequent cell type–specific proliferation. Extending lineage tracing to adulthood determined that embryonic cells undergo spatially heterogeneous three-dimensional growth associated with distinct environments. Strikingly, giant clusters comprising almost half a ventral lobe suggest lobe-specific dominant-like growth behaviours. We show substantial hepatocyte polyploidy in juveniles representing another hallmark of postembryonic liver growth. Our findings uncover heterogeneous progenitor contributions to tissue architecture-defining cell type proportions and postembryonic organ growth as key mechanisms forming the adult liver., Peer reviewed

Supplementary figures: 1-3, Orai1 is the pore-forming subunit of the Ca2+-release activated Ca2+ channels that mediate store-operated Ca2+ entry (SOCE) in excitable and non-excitable cells. Two Orai1 forms have been identified in mammalian cells, the full-length variant Orai1α, and the short form Orai1β, lacking the N-terminal 63 amino acids. Stem cells were isolated from non-tumoral breast epithelial cells of the MCF10A cell line, and the most representative ER+ , HER2 or triple negative breast cancer cell lines MCF7, SKBR3 and MDA-MB-231, respectively. Orai and TRPC family members expression was detected by RT-PCR and Western blotting. Changes in cytosolic Ca2+ concentration were analyzed by confocal microscopy using Fluo 4 and the spheroid-forming ability and self-renewal was estimated in culture plates coated with pHEMA using a cell imaging system. Here, we have characterized the expression of Orai family members and several TRPC channels at the transcript level in breast stem cells (BSC) derived from the non-tumoral breast epithelial cell line MCF10A and breast cancer stem cells (BCSC) derived from the well-known estrogen receptor positive (ER+), HER2 and triple negative cell lines MCF7, SKBR3 and MDA-MB-231, respectively. Furthermore, we have evaluated the mammosphere formation efficiency and self-renewal of the BSC and BCSC. Next, through a combination of Orai1 knockdown by iRNA and the use of MDA-MB-231 KO cells, missing the native Orai1, transfected with plasmids encoding for either Orai1α or Orai1β, we show that Orai1 is essential for mammosphere formation and self-renewal efficiency in BCSC derived from triple negative and HER2 subtypes cell cultures, while this channel has a negligible effect in BCSC derived from ER+ cells as well as in non-tumoral BSC. Both, Orai1α, and Orai1β support SOCE in MDA-MB-231-derived BCSC with similar efficiency, as well as COX activation and mammosphere formation. These findings provide evidence of the functional role of Orai1α and Orai1β in spheroid forming efficiency and self-renewal in breast cancer stem cells., This research was supported by PID2019-104084 GB-C21, PID2019-104084 GB-C22 and PID2022-136279NB-C21 funded by MCIN/AEI/10.13039/501100011033 and by “ERDF A way of making Europe”, and Junta de Extremadura-Fondo Europeo de Desarrollo Regional (FEDER; Grant IB20007 and GR21008) to JAR.

output position. Thus, for the tunneled wave packet, the output position also changes with the dc
driving strength, but it can be well preserved except the strong driven case.
Apart from the above trajectory analysis, we also simulate the full wave packet dynamics in Figs.
S4E-S4H, which correspond to α = π/40, π/30, π/20, and π/12, respectively. One can see that an increase
of the driving strength can efficiently enlarge the splitting ratio of wave packet. Nevertheless, there
exist certain severe issues in the above beam splitting scheme. Firstly, at a relatively weak driving (Fig.
S4E), the tunneling time instant is close to the output plane because the wave packet spends more time
reaching the Brillouin zone boundary. After the LZT, the split wave packets cannot be well separated,
which is not applicable in the practical beam splitter. Secondly, at a moderate driving (Figs. S4F and
S4G), one can obviously observe the drift of wave packet at the original band branch. Finally, at a
strong driving (Fig. S4H), more LZTs happen within the same propagation distance Mtot , making the
two-branch splitting scheme into a multi-branch one. In conclusion, in the dc-driven beam splitter, it
is very difficult to simultaneously control the splitting ratio and preserve the wave packet trajectory.

[Background] Managing the inflammatory response to SARS-Cov-2 could prevent respiratory insufficiency. Cytokine profiles could identify cases at risk of severe disease., [Methods] We designed a randomized phase II clinical trial to determine whether the combination of ruxolitinib (5 mg twice a day for 7 days followed by 10 mg BID for 7 days) plus simvastatin (40 mg once a day for 14 days), could reduce the incidence of respiratory insufficiency in COVID-19. 48 cytokines were correlated with clinical outcome., [Participants] Patients admitted due to COVID-19 infection with mild disease., [Results] Up to 92 were included. Mean age was 64 ± 17, and 28 (30%) were female. 11 (22%) patients in the control arm and 6 (12%) in the experimental arm reached an OSCI grade of 5 or higher (p = 0.29). Unsupervised analysis of cytokines detected two clusters (CL-1 and CL-2). CL-1 presented a higher risk of clinical deterioration vs CL-2 (13 [33%] vs 2 [6%] cases, p = 0.009) and death (5 [11%] vs 0 cases, p = 0.059). Supervised Machine Learning (ML) analysis led to a model that predicted patient deterioration 48h before occurrence with a 85% accuracy., [Conclusions] Ruxolitinib plus simvastatin did not impact the outcome of COVID-19.
