Correction: Blastulation time measured with time-lapse system can predict in vitro viability of bovine blastocysts

Abstract

Figures

Full text

After publication of this article [1], concerns were raised that Fig 2 in [1] was duplicated from Figure 3 in a previous article [2] by a different author group, and that [2] was not cited in [1].

During editorial follow up on this issue, the corresponding author stated that Fig 2 in [1] was included in error.

Owing to the concerns about duplication with previously published content [2], published in 2010 by Oxford University Press [2], which is not offered under a CC BY license, this article [1] was republished on June 24, 2024, to correct the Fig 2 error. The updated figure reports demonstrative images of individual cultures in 16 microwell plates to monitor embryonic development in cattle. These images are from the original experiments reported in [1] at day 7.5 post IVF (S5 File). Replicate images from the time of the original experiments and images from earlier and later repeat experiments are provided here in S1–S4 Files. Additional data underlying S1 Table and supporting the embryo measurements in [1] are provided here in S6–S15 Files.

An member of the Editorial Board reviewed the concerns and stated that the updated Fig 2 supports what is stated in the published article, ‘During in vitro culture, 16 presumptive zygotes were individually (Fig 2) monitored using the Primo Vision TL equipment (Vitrolife, Sweden) that takes images every 15 minutes from day 1 to 7.5 post IVF.’ [1]. They also advised that the data provided with this notice are sufficient to support the article’s key results as required by the PLOS Data Availability policy.

The corresponding author also provided some clarifying information about the methodology used in [1]:

S6 FileUnderlying data supporting the summary in S1 Table in [1].(XLSX)

S7 FileSupporting data for S1 Table and the embryo measurements in [1].The times to divisions 2, 4, 8, etc. were processed individually, and the kinematics of the embryo was recorded in two parts because the Primovision (R) software did not allow continuous video recording for the 7.5 days post IVF. S7–S13 Files correspond to three batches of work.(WEBM)

S8 FileSupporting data for S1 Table and the embryo measurements in [1].The times to divisions 2, 4, 8, etc. were processed individually, and the kinematics of the embryo was recorded in two parts because the Primovision (R) software did not allow continuous video recording for the 7.5 days post IVF. S7–S13 Files correspond to three batches of work.(WEBM)

S9 FileSupporting data for S1 Table and the embryo measurements in [1].The times to divisions 2, 4, 8, etc. were processed individually, and the kinematics of the embryo was recorded in two parts because the Primovision (R) software did not allow continuous video recording for the 7.5 days post IVF.

S10 FileSupporting data for S1 Table and the embryo measurements in [1].The times to divisions 2, 4, 8, etc. were processed individually, and the kinematics of the embryo was recorded in two parts because the Primovision (R) software did not allow continuous video recording for the 7.5 days post IVF.
