RETRACTED: Effect of the solid retention time in the obtention of polyhydroxyalkanoates [version 1; peer review: awaiting peer review]

Abstract

At the request of the authors, the article titled "Effect of the solid retention time in the obtention of polyhydroxyalkanoates" [version 1; peer review: awaiting peer review]. F1000Research 2021, 10:864 (https://doi.org/10.12688/f1000research.28852.1) has been retracted from F1000Research. Since publication of the article, the corresponding author has notified the Editorial team that this work was originally performed at University of A Coruña with the involvement of María C. Veiga and Christian Kennes, who were not notified regarding the submission of this manuscript or listed as authors. After discussion with all parties, including contact with the corresponding author’s institution, it was agreed that the article would be retracted in order to correct the academic record. As the article contains content which potentially should not have been made publicly available the content of the article has been removed. The authors apologise for this honest error.

Hybrid cancer stem cells utilise vascular tracks for collective streaming invasion in a metastasis-on-a-chip device

“…Having first optimised co-culture in the microfluidic chip and analysis of invasion (Figure S1) (Scemama et al, 2023), we proceeded to assess the effect of a microvasculature on the mode of invasion of OSCC cells. We cultured the CA1 and LUC4 OSCC cell lines in the presence and absence of HUVECs in the microfluidic chip.…”

“…Detailed protocols for cell culture in the microfluidic chip are available in our recent method article (Scemama et al, 2023).…”

“…The CA1 and LUC4 cell lines were both previously derived in our laboratory, from biopsies of OSCC of the floor of the mouth. The CA1 cell line was also previously retrovirally transduced with GFP to produce a GFP+ derivative of this cell line (Scemama et al, 2023). The NTERT cell line is a hTERT-immortalised epidermal keratinocyte cell line (Dickson et al, 2000).…”

“…FIJI, ICY and Developer Toolbox (GE Healthcare) were used for image analysis. Detailed protocols for image analysis are available in our recent method article (Scemama et al, 2023).…”
